Basic Shell Scripting: Chapter-I

If you are not a programmer and you are doing a repetitive task daily by issuing some commands to complete a task then, you can write a shell script to do the same thing for you by issuing a single command. It’s not required to type the command every time. Just write down the commands in a shell script and execute the script to complete your task. It’s so simple. In this article I will give you some basic knowledge about shell scripting.

Here are the steps to write a shell script:

• Use a editor like “vi” or “vim” to write the script

  • vi clear.sh

• Set execute permission to your script

  • chmod +x clear.sh

• Execute your script

  • /bin/bash clear.sh
     or
    bash clear.sh
     or 
    /bin/sh clear.sh
     or 
    sh clear.sh
     or 
    ./clear.sh
