Cancer

Cancer is not a mild disease. The initial step in the treatment of cancer detection correctly is that the symptoms that appear on the patient's body is truly malignant cancer cells. This detection can be done by examination of biopsy, so that the treatment step can be performed quickly and accurately. The next step is a therapeutic treatment in a conventional manner. But in fact this way of treatment of cancer often can not be solved in total. Here, the role of medicinal plants / herbs.



The main role is to increase endurance herbal body of the patient and locate cancer cells so that cancer cells do not easily spread, and more easily removed, also non-toxic making it safer for the patient's body. Examples are the medicinal plants of rodent tuber extract (Typhonium Flagelliforme). In use, these herbs can be used in conjunction with conventional treatment (surgery, chemotherapy, radiotherapy and hormonterapi) or after conventional treatment has been completed. Because the drug of rodent tuber extract can help reduce the effects of conventional treatments.The number of cancer patients in Indonesia is not known with certainty, but the increase from year to year can be proven as one cause of death. Only a few cancers that can be treated satisfactorily, especially if treated while still an early stage. The success of treatment is determined by the type of cancer, cancer staging, general condition of patient, and patient effort to recover.What is cancer?Cancer is a disease caused by the growth of body tissue cells are not normal. Cancer cells will grow rapidly, uncontrollable, and will continue to divide, then infiltrate into the surrounding tissue (invasive) and continue to spread through the connective tissue, blood, and attack vital organs and spinal cord. Under normal circumstances, cells will only divide if there is replacement of cells that have died and broken. Instead cancer cells will divide continues even if the body does not need it, so it will happen accumulation of new cells are called malignant tumors. Stacking cells are urgent and damage normal tissue, thus disturbing the organs they occupy. Cancer can occur in various tissues in various organs in each body, from feet to head. When cancer occurs on the surface of the body, will be easily detected and treated. But if there is in the body, the cancer will be difficult to know, and sometimes - sometimes have no symptoms. If symptoms occur, they usually have an advanced stage that it is difficult to treat.The difference tumors and cancerTumors are of two kinds of benign and malignant tumors. Benign tumors only grow and grow, not too dangerous, and not spread outside the network. Whereas malignant tumors are cancers that grow rapidly and uncontrolled and damaging other tissue.

Type - type of cancer known today are:

- carcinoma
That type of cancer that originates from cells lining the surface of the body or surface of the body channels, such as tissues such asskin cells, testes, ovaries, mucous glands, melanin cells, breast, cervix, colon, rectum, stomach, pancreas, and esophagus.

- Lymphoma
That type of cancer that originate from blood-forming tissues,such as lymphoid tissue, lacteal, spleen, various lymph nodes,thymus, and bone marrow. Specific lymphomas includeHodgkin's disease (cancer of the lymph nodes and lymph)

- Leukemia
This type of cancer does not form a tumor mass, but meet theblood vessels and interfere with normal blood cell function.

- Sarcoma
That type of cancer where the network is supporting the bodysurface such as connective tissue, including cells - cells founddiotot and bone.

- Gliomas
Ie nervous system cancers, such as glial cells (supporting tissue)in the central nervous system.

- Carcinoma in situ
That is the term used to describe abnormal epithelial cells are still limited in certain areas so it is still considered prainvasif lesion(abnormality / injury that has not spreading)

 factors that cause cancerThe cause of cancer is usually not known for certain because the causes of cancer can be a combination of a set of factors, genetic and environmental. But there are several factors that allegedly increases the risk of cancer, as follows:HeredityGenetic factors cause some families have a higher risk of developing certain cancers when compared with other families.The type of cancer tends to run in families is breast cancer, ovarian cancer, skin cancer and colon cancer. For example, a woman's risk for cancer increased 1.5 s / d 3 times if the mother or sister had breast cancer.Environmental Factors- Cigarette smoking increases the risk of lung cancer - lung, mouth, larynx (vocal cords), and bladder.- Ultraviolet light from the sun- Ionizing radiation (which is carcinogenic) is used in x-ray beam generated from nuclear power plants and atomic bombs that could reach a great distance. For example, people who survived the atomic bombs on Hiroshima and Nagasaki in World War II, the high risk of developing cancer of blood cells, such as leukemia.Factors Foods that contain chemicals.Food also can be another important risk factor for cancer, particularly cancers of the digestive tract. Examples of foods that can cause cancer are:- Smoked and pickled foods (in the form of pickles) increase the risk of gastric cancer- Drinks that contain alcohol cause higher risk for esophageal cancer.- Substance of food coloring- Heavy metals such as mercury are often found in contaminated seafood such as shellfish, fish, etc..- A variety of foods (sweet, flour) are processed in excess.VirusViruses that can and suspected of causing cancer, among others:- Papilloma virus causes genital warts (genital) presumably is one cause of cervical cancer in women.- Cytomegalovirus causes Kaposi's sarcoma (cancer of the blood vessel system is characterized by red skin lesions)- Hepatitis B virus can cause liver cancer.- Epstein - Bar (in Africa) causes Burkitt's lymphoma, whereas in China these viruses cause cancer of the nose and throat. This occurs because of environmental and genetic factors.- Retro Virus in humans such as the HIV virus causes lymphomas and other blood cancers.Infection- The parasite Schistosoma (bilharzia) may cause bladder cancer due to chronic irritation of the bladder. However, other chronic irritants do not cause cancer.- Infection with Clonorchis that causes cancer of the pancreas and biliary tract.- Helicobacter pylori is a bacterium which may be the cause of gastric cancer, and the alleged injury and this bacterium causes chronic inflammation of the stomach so as to increase the speed of the cell cycle.Behavioral factors- The behavior in question is smoking and eating foods that contain lots of fat and cured meats are also drinkers of alcoholic beverages.- Behavior that is sexual intercourse early age and frequently changing sexual partners.Hormonal balance disordersThe hormone estrogen stimulates the growth of cell function that tends to encourage the occurrence of cancer, while progesterone protects the occurrence of excessive cell growth. - There is a tendency that the excess hormones estrogen and progesterone deficiency leading to increased risk of breast cancer, cervical cancer, uterine cancer and cancer of the prostate and testicles in men.Psychological factors, emotional- Stress can cause severe disruption to the company the balance of the body cell. Continuous state of tension which can affect the cells, where cells become hyperactive and the changing nature of the malignant cancer causing.Free radicals- Free radicals are an atom, group of atoms, or molecules that have unpaired electrons that are free dilingkaran outside.Sources - sources of free radicals which are:1. Free radicals are formed as byproducts of metabolic processes.2. Free radicals enter the body in the form of chemical toxins from food, drinks, polluted air, and ultraviolet rays from the sun.3. Excessive production of free radicals at the time we eat too much (have an impact on metabolic processes) or when we are in a state of excessive stress, whether physical stress, psychological, or biological.
Risk Factors and Symptoms of CancerHormonal Risk FactorsThe hormone estrogen can function as promoters for certain cancers such as breast cancer and endometrial cancer. Women who have menstrual estrogen levels are high, then the increased risk of developing breast cancer in women who menstruate early and reach menopause later. Contain late or not having children may increase the risk of breast cancer.Mental Factors, Emotions PsychicDisruption of the emotions can cause or aggravate cancer such as stress, resentment, hatred, or hurt (pain). The role of psychological factors in cancer can be in several ways, including: stress, or grudges that influenced the development of cells into the wild and the effects that weaken the immune system T cells that are not able to eliminate cancer cells are formed.Some of the factors that are protective against cancer formation, namely:- The hormone progesterone is protective against cancer by inhibiting the stimulatory effect of estrogen. The hormone progesterone increases during pregnancy and during lactation in women therefore, women who breastfeed for at least 6 consecutive months - also, women who are pregnant several times, will reduce the risk of breast cancer.Symptoms - symptoms of cancerSymptoms of cancer that arises in general depend on the type or organs affected are:Pain may occur as a result of widespread tumor pressing surrounding nerves and blood vessels, immune and inflammatory reactions against growing cancers, and pain is also caused by fear or anxiety.Bleeding or unusual discharge, such as saliva, coughing or vomiting blood, persistent nosebleeds, nipple fluid that contains blood, bloody fluid hole intercourse (between menstrual / menopause) blood in the stool, blood in the urine.Changes in bowel habitsLosing weight quickly due to lack of fat and protein (kaheksia)Lumps in the breastDigestive disorders, such as difficulty swallowing continuously.Deafness, or a voice - a voice in the ear that persisted.Wounds that do not heal - healChanges in moles or skin of the strikingSymptoms of Cancer is specifically based on the type of cancer experienced by:Brain CancerHeadaches in the morning and decrease at midday, epilepsy, weakness, numbness in arms and legs, difficulty walking, drowsiness, abnormal changes in vision, changes in personality, changes in memory, it is difficult to speak.Oral cancerThere are canker sores in the mouth, tongue and gums that do not heal.Throat CancerPersistent cough, hoarseness or husky.Lung CancerCough continued - again, sputum mixed with blood, pain in the chest.Breast CancerA lump, thickening of the skin (tickening), changes in shape, itching - itching, redness, pain not associated with breastfeeding or menstruating.Digestive tract cancersThe presence of blood in the feces marked with bright red or black, malaise continues - constantly on the stomach, lump in the abdomen, pain after eating, weight loss.Cancer uterus (uterine)Diperiode bleeding - period coming months, when menses extravasation unusual and incredible pain.Ovarian cancer (ovarian)In the next phase before symptoms appear.Colon CancerBleeding in the rectum, blood in the stool, change in bowel movements (diarrhea persistent or difficult bowel movements).Bladder or Kidney CancerThere was blood in the urine, pain or burning during urination, frequency or difficulty urinating, pain in the bladder.Prostate CancerUrine is not smooth, continuous pain in the back waist, penis and upper thigh.Scrotal cancer / testisA lump in the scrotum, scrotal size reservoirs in the enlarged and thickened suddenly, pain in lower abdomen, breasts enlarged or soft.LymphomaEnlarged lymph nodes, rubbery, itching - itching, sweating at night time sleep, fever or weight loss for no apparent reason.LeukemiaPallor, chronic fatigue, weight loss, often subject to infection, easily hurt, pain in bones and joints, nosebleeds.Skin CancerLumps on the skin that resemble warts (hardened like a horn), an infection that does not heal - heal, the spots change color and size, pain in certain areas, changes in skin color of the spots.ComplicationA frequent complication in cancer patients is an infection that is in people with advanced cancer. Infections caused by lack of protein and other nutrients as well as immune system suppression that often occurs after conventional treatment.

diagnosis of Cancer

Early Detection of Cancer:

Efforts to cancer detection to date is with Digital Infrared Imagingor Digital Infrared Imaging (PID). This technique to monitor the health of breast and cervix in women for the presence ofprecancerous process. PID working principle is that objects at a given temperature will emit electromagnet radiation from the surface waves that are invisible, where the maximum intensityoccurs at a wavelength of infrared light region. Chemical activityand blood vessel activity in the precancerous tissue surroundingthe growing always higher than normal tissue.

Some screening tests that can be done at home, such as breast self examination every month can greatly help women detectbreast kaknker.

Checking the scrotum can help men detect the cancer early so it can be cured if found at an early stage.

Regularly check the presence of open sores in the mouth that does not heal - heal to detect oral cancer at an early stage.

Determining Stage of cancer

If the cancer was discovered, examination staging (staging) of cancer helps the doctor plan appropriate treatment anddetermine prognosis course of their illness. Staging can be done using:

1. Scanning / scanning (eg liver or bone scan)

2. Staining of the tissue so that if there is cancer pathologicaltissue can be known.

3. CT (Computed Tomography) or MRI (Magnetic ResonanceImaging)

4. Mediastinoskopi

5. Bone marrow biopsy.

Sometimes surgery is necessary to determine the stage ofcancer. For example, a laparotomy (abdominal surgery) allows the surgeon to remove or treat colon cancer while determining thespread of cancer to nearby lymph nodes.

Cancer Treatment1. Conventional Treatment- Treatment with ChemotherapyThe working principle of this treatment is to poison or kill cells - cancer cells, controlling the growth of cancer cells, and stop its growth so as not to spread or to relieve symptoms caused by cancer. Chemotherapy is sometimes the first choice for dealing with cancer. Chemotherapy is a systematic, in contrast with radiation or surgery that is local, so chemotherapy can reach cancer cells that may have spread and spread to other parts of the body. The use of chemotherapy varies in each patient, sometimes as a primary treatment, in other cases performed before or after surgery and radiation. The success rate of chemotherapy also varies by type of cancer. Chemotherapy is usually done in hospitals, private clinics, doctor's office, operating room (although rarely done) and also at home (by the nurse, the patient himself, or other family members).Side effects of chemotherapy is to decrease the number of blood cells (will be back to normal about a week later), infection (characterized by fever, sore throat, burning sensation when urinating, chills and flushed the wound, swelling, and warmth), anemia, bleeding such as nosebleeds, hair loss, sometimes there are complaints such as itching and dry skin, nausea and vomiting, dehydration and low blood pressure, constipation / constipation, diarrhea, nervous system disorders.- Treatment with Radiation Therapy (Radiation)Radiation therapy is usually done before or after surgery to shrink the tumor. Radiation is done in an attempt to destroy the tissues that have been affected by cancer.Radiation side effects are nausea and vomiting, decreased number of white blood cells, infection / inflammation, skin reactions such as sunburn, fatigue, pain in the mouth and throat, diarrhea and can lead to baldness.- Treatment with surgerySurgery is the treatment of cancer of the oldest. Some cancers can often be cured only with surgery if done at an early stage.- Treatment with combination therapyFor some cancers, the best treatment is a combination of surgery, radiation, and chemotherapy. Surgery or radiation to treat cancer that land is limited, whereas chemotherapy aims to kill cancer cells that are beyond the reach of surgery or radiation.Sometimes radiation or chemotherapy before surgery to reduce the size of the tumor or after surgery to destroy remaining cancer cells that may remain.2. Herbal MedicineHerbal treatment is a treatment using a variety of extracts from plants (medicinal plants), for example, extracts from rodent tuber (Extract Typhonium Flagelliforme) combined with other natural materials are processed in a modern, which can help to detoxify the blood and tissues stimulates the immune system bodies to work together to eradicate cancer cells. Herbal treatment is an alternative treatment that has been widely proven efficacy than treatment performed in a modern / conventional.The use of herbs to treat cancer do not appear out of nowhere.There are several approaches that underlie the treatment of the raw materials, namely sebabagi follows:1. The concept of the research results that cancer is reversible (can be normal again)2. The concept of inhibiting cancer growth. Cancer grows because of environmental carcinogens and genetic mutations that support growth. If these environmental carcinogens and eliminated, the cancer growth is inhibited.3. The concept of cancer cell aging. If growth is inhibited, the cancer cell does not have a chance to flourish, then old and die.4. The concept of strengthening other cells around the cancer.Developing cancer by attacking cells that are nearby, so that by strengthening the surrounding healthy cells will form the cell's defense can hold the cancer cells.

Business Cancer Prevention and Therapy of Mental

Prevention in General

Prevention of cancer is a common way of reducing exposure tocarcinogenic materials, such as not smoking, avoiding foods high in fat, high-fiber foods such as vegetables and fruits, Akif physicallife, striving for the ideal body weight, and live a healthy pattern.Prevention can also be done by screening or screening for the possibility of getting cancer. Cancer screening test is intended to determine the possibility of cancer so that it can reduce the number of deaths from cancer because if cancer is found at a very early stage, where the cancer has not spread further, the cancer usually can be treated and provide optimal results.

Mental therapy

Some things to do in terms of mental therapy for patients withcancer are:
managing stress
Recognizing the stress
Moral support in cancer patients
Stay active and have fun
Empathize (understand the severity of the mental burdenexperienced by cancer patients to support recovery)
Optimistic in the running life
Dispose of revenge and hatred
Prayer therapy (closer to God)

Linux Basic

Preliminary
     
Although his subjects I called a Graphical User Interface (GUI I), but his materialis a form of Linux and Database. Indeed, had discussed also about the GUI in Linux.This paper contains the basic foundation of Linux, which consists of the History of Linux, the command structure in Linux,Directory and File, Process Standard File, User and Communication Anar VIM Text Editor.
  


                                 
Graphical User InterfaceI. IntroductionIn an Operating System (OS) or an application, in need of an interfaceor interface to the user in order to run the OS or application area with ease.There are two types of interfaces, namely:
             
1. Text Based
             
2. Graphical User InterfaceText Based: text-based interface.
                     
Example: DOS or Console on LinuxGUI: Graphical Interface
                     
Example: OS Windows or Desktop Environment in LinuxIn view of the GUI is easier and exciting in the appeal text based, because it has elements ofcolor and graphics that have 2 or 3 dimensional shapes including images, on appealText Based having only text.
      
Today, a growing number of applications and OS that implement a GUI forconvenience and performance of applications and the OS they will be, in addition to hardware technology as wellis very possible the application of better GUI.
   
To implement the GUI, in requiring a higher hardware specification of the textbased, namely: The computer screen, memory, processor and hard drive. But with conditionsCurrent hardware, it's not a problem in the application GUI.
    
In this lecture, we will discuss the application GUI in Linux OS and learnsome Linux commands and a MySQL database using PHPMyAdmin anddo not miss learning about the language of Generation-4.1. History of Linux

    
Linux, created by Linux Torvalds, a student of University of Helsinki in Finlandin 1991, the beginning of her is because of dissatisfaction from the Minix Licenserestrict its use only for education (preventing from commercial purposes).He made the Linux Kernel, which is a Linux core, on top of Minix by usinglanguage C. Linux has a GNU license, a license that allowssomeone to distribute and modify the source code freely andfree of charge.
     
Making Linux is done in mutual cooperation by many programmers whomost C / C + + Programmers around the world via the internet.
    
Linux is a penguin logo, because during the development of Linux, Torvalds hadin antuk by Penguin in a zoo that causes fever and its selfhe aspires to allow others to "fever" of Linux.
    
Linux own name in the adaptation of his name Linus.
       
Currently, Linux has some based Graphical Desktop Environment, inAmong them are:1. KDE (K Desktop Environment)2. GNOME (GNU Network Object Model Environment)



    
3. Icewm
    
KDE and GNOME are 2 Desktop Environment (DE) that runs on the popular
    
Linux and is a DE that requires high hardware specifications require
    
because it has a graphical display with high resolution, even for
    
apply the latest feature from the User Interface was also, like the 3D desktop effects in
    
need support graphics card or Graphical Card.

       
Linux also has a text-based interface that is often called the console or CLI
    
(Command Line Interface). To apply the Desktop Environment in need
    
The hardware specs are higher than the Command Line.

    
Advantages of using Linux

      
1. More secure
        
Separate the Linux file and directory permissions for normal user and super user or
    
the root. A normal user to give access only at certain directory in a folder for
    
store data, which is in the folder / home / name. Therefore, the security files
    
system and other files in the case of likely erased by the user.In addition to
    
It also requires a password setting system of the Super User.

       
2. More resistant to virus
        
Since the separation of the file access, lack of enabling a virus through the file
    
the system. In addition, Linux has no Registry in the know is where
    
the virus hides. In Linux there is also no exe file that can be jangkiti virus
    
and can spread the virus.

      
3. Free and can disseminate
         
Linux has a GNU license, a license that allows a person
    
to promulgate, modify and use Linux for free.

      
4. Hardware compatible with the old
        
Linux can be installed on the old hardware and it certainly does not apply in the GUI
    
this. TSB old hardware can be used for servers that do not require
    
The GUI. In this case, Linux requires low hardware specifications.

    
Losses Using Linux

    
1. Its few users
         
This also resulted in fewer people who can make the event
    
ask
        
fellow Linux users.

    
2. Support from the company does not exist
            
Especially for Linux is free, then the support and rely on manual
    
the community. There is no
        
guarantee against error and the consequences of error.

    
Some examples of Distribution
    
Here are some examples of linux distributions, namely:

 

    
- Fedora - Suse
    
- Red Hat - Mandriva, Ubuntu



                                         
The command structure in Linux

     
Linux has a GUI and Console for user interfaces. On this occasion we will
     
discuss the console on Linux is made in the interface for write commands.

     
On the console, there are two types of prompts, namely:

     
- $ Declared a regular user with a shell prompt type Korn shell, Bourne Shell or
     
Bourne Again
          
Shell.
     
-% Claimed regular user with a shell prompt type C Shell
     
- # Declare a prompt for the super user (root)

     
While the command structure in Linux on the console is as follows:

     
nama_perintah [options] [arguments ...]
     
description:

     
square brackets that is therein are optional, there can be
     
not

          
 point mark three times (...) states that the component in front of this sign can be repeated
             
several times
          
 nama_perintah can be a command that already exists in linux / unix shell scripts or
              
and application, stating the command to be executed by the shell
          
 options (options) to alter or add to the default action of the command
          
 argument stating the object to be processed by the command, this section usually
             
the form of files, but there also contains data that is processed.

     
Example:

     
Syntax: ls

     
Function: To display the list of file names

     
Example:

     
[Sofwan Sofwan @ ~] $ ls

     
note

     
[Sofwan Sofwan @ ~] $ ls-l

     
total of 4

     
-Rw-r-r - 1 Sofwan Sofwan 25 records 2011-03-05 14:33

     
Description:

      
- The-l parameter: For a long listing format

      
--Rw-r-r -: The structure of a file security

      
- Sofwan Sofwan: This file is owned by the user: Sofwan and group: Sofwan

      
- 25: Size of bytes

      
- 2011-03-05 14:33: Date of file creation

      
- Note: The name of the file

     
For more complete information about a command, you can use the command
     
as follows:

     
nama_perintah-help

     
or

     
man nama_perintah

     
Some of the options that exist in the ls command is:

          
--A - all show all files, including those at the start with a point

          
--F Not the sort, enable-au and me disable-ls -
                
color

          
--H-human readable by using the-l also, print size in the format
                
which

                                             
easy to read.

          
- Using the-l long listing format

          
--R-reverse in reverse order when sorting

     
For another example of the syntax is:

     
[Sofwan Sofwan @ ~] $ df - total

     
Filesystem Size Used Avail Use% Mounted on

     
/ Dev/sda5 20G 13G 66% 6.4 G /

     
/ Dev/sda7 9.7 G 9.7 G 5.3 G 46% / home

     
17g total 30G 12G 60%

     
Description:

     
df: syntax to determine the condition of the hard drive

     
parameters - total: Print a total value

     
Ls In addition, there are several other commands, such as:

          
- Pwd → To know the current directory

     
Example: [Sofwan Sofwan @ ~] $ pwd

                    
/ Home / Sofwan

          
- Whoami host name → To know oneself

     
Example: [Sofwan Sofwan @ ~] $ whoami

                                 
Sofwan

  

          
- Date → To know the current date in the computer

                
Example: [Sofwan Sofwan @ ~] $ date

                                
Sun Mar 6 14:17:33 CDT 2011

                                                  
Changing Password

     
Before discussing change your password, we learn how to create a user, which is as follows:

          
1. Enable user superuser, by the way:

                 
[Sofwan Sofwan @ ~] $ su

          
2. You will be ask your password, enter its password:

                  
[Sofwan Sofwan @ ~] $ su

                  
password:

          
3. [Root @ Sofwan Sofwan] #

                 
Prompt at the top indicates the user is a superuser or root.

          
4. Enter the following syntax: adduser nama_user, eg, user name is Herman.

                 
[Root @ Sofwan Sofwan] # useradd herman

          
5. Can also use the following options:

                 
-D home directory

                  
-G (primary group)

                  
-M (home directory)

     
Once a user is formed, we can provide the password, by the way:

      
1. At the root account:

         
[Root @ Sofwan Sofwan] # passwd herman

         
Changing password for user ali.

         
Password:

     
2. Enter a password, and then appears:

         
[Root @ Sofwan Sofwan] # passwd herman

         
Password:

         
BAD PASSWORD: it is based on a dictionary word

         
Retype new password:

        
After typing the password for his second time, the system can comment on the password

        
already, such as BAD PASSWORD. If you want to keep using the password they will be,

        
continue to retype the password Retype new or TSB.

     
Password that has been formed, can we change with the same command, ie: passwd.
     
If the login is active in the user that will change his name, enough with the passwd, but if

    
active login is root, then the user needs to type his name, like: passwd herman.Adding Users and password and change it we can do with a GUI.OnMandriva, we go into the Mandriva Linux Control Center → System → Manage Users onSystem.To enter the Mandriva Linux Control Center in need the root password.

                                             
Figure 1: User and group settings

    
In the User and Group settings menu you can add, delete and edit userand group.

   


                                                

                                                                  
Directories and FilesA. File TypesThere are 7 types of file types on Linux and type of encoding, namely:

     
1. Regular Files -

     
2. Directories d

     
3. Character Device Files c

     
4. Block Device Files b

     
5. Local Domain Sockets s

     
6. Named Pipes p

     
7. Symbolic Links lThis file type can be in the know by using the command ls-l. In the example above, for example:[Sofwan Sofwan @ ~] $ ls-ltotal of 4-Rw-r-r - 1 Sofwan Sofwan 25 records 2011-03-05 14:33In the example above, the beginning of the sentence above results are -, means that the file record isregular file.B. Operations on the Directory

            
Create Directory.

            
Command: mkdir [OPTION] ... DIRECTORY ...
            
Example: mkdir data → Create a data directory

     
- Removing Directories
            
Syntax: rmdir [OPTION]
            
Example: rmdir remove directory data → data
            
Note: The directory must be deleted empty

                   
To delete all data in the following directory within it, you canuse
            
command: rm-rf nama_direktori
            
Example: rm-fr my data
            
Description: Delete the following directory of my data in its data without anyquestion
                                  
confirmation.
            
      
- Rename the directory
            
Syntax: mv [OPTION] ... SOURCE DEST
            
example: mv data data1
            
Description: rename data directory into the directory data1


         
- Copying Directory
                 
Syntax: cp [OPTION] ... SOURCE DEST
                 
Example:
                 
[Sofwan @ Sofwan data2] $ cp * ../data3
                 
Description: Copy all files and directories into the folder data3, which
     
situated
                                       
parallel to the data2 directory.
       
C. Operations on files

         
Creating a File

                      
Creating a file can be done by storing document files into the
     
a folder,
                      
eg, typing a letter in the application writer and store its files in the document
     
certain.

           
- Change the file

             
To change the content, ie by opening the file in the application
     
accordance with the
            
types of files and make modifications, then save again.
            
To rename a file, it can be done by:

            
Syntax: mv [OPTION] ... [-T] SOURCE DEST
            
Example: mv my data dataku1

          
- Delete a file
             
By the way:
             
Syntax: rm [OPTION] ... FILE ...
             
example: rm record
                    
Description: After executing the above commands, you will be in confirmation
     
for right-
                                   
completely remove the file.

           
- Copying files
             
Syntax: cp [OPTION] ... SOURCE DEST

             
Example:
             
[Sofwan @ Sofwan data2] $ cp note ../data3
              
Description: Copying files into the folder data3 record, which lies parallel
     
with
                                  
data2 directory.

           
Directory and file operations can also be done by using a file manager,
