Hello Everyone !!
***Hope All are doing well ***
Today In this post we will create our own command and run its our terminal 🙂
Have a Look —-
For Example , I want to create commands with name of sahil,love,linux, I am creating a simple script for that….
Lets start :-
[root@sahil ~]# owncommand.sh
#!/bin/bash
sahil()
{
echo “Hello This is my first own command “.
}
love()
{
cat /etc/issue
}
linux()
{
date
}
wq!
Save and Quit
Make it as Executive file :-
[root@sahil ~]# chmod +x owncommand.sh
Check permission :-
[root@sahil ~]# ll owncommand.sh
-rwxr-xr-x 1 root root 116 Jul 11 15:21 owncommand.sh
If I tried to run command like sahil then It will give me error as command not found:- Lets try
[root@sahil ~]# sahil
bash: sahil: command not found
So we need to run a command to rectify this problem :-
[root@sahil ~]# . owncommand.sh <—— To Installed Command in Shell Memory
Lets try again :-
[root@sahil ~]# sahil <———– 1st command
Hello This is my first own command .
[root@sahil ~]# love <———– 2nd command
CentOS Linux release 6.4 (Sahil) <——- updated /etc/issue file 🙂
[root@sahil ~]# linux <———– 3rd command
