    Each command is stored in one of the PAth… that u see by $PATH command.
    you can write your own script.. and put that in one of these paths..
    that script will work as a command

      Actually, when ls command is executed then at that time which are the system calls are executed?

      • pushpa says:

        view “strace ls” command to check what all system calls has been called due to ls command.It first exec the shell & then through multiple open read & mmap it fetches the information from the hard disk via system calls & provide the list back to user shell.
