How to find command invoked path

I have exported my script to PATH variable. So from anywhere, I may invoke my script but I have to know from which path I am invoking the script.

Script present in the path /home/raja/scps/shell/s1.sh

export PATH=$PATH:/home/raja/scps/shell/s1.sh.

I will run the script as follows:

1st example:

root@raja-H97-D3H:/home/raja#s1.sh

I want to know the path: /home/raja

2nd example:

root@pmt-H97-D3H:/home/pmt/tmp/p1/p2#s1.sh

I want to know the path: /home/pmt/tmp/p1/p2

The current working directory from where the script was invoked is available in the PWD environment variable inside the script.

Consider this example script:

#!/bin/bash

echo $PWD

Add it to your path, and invoke it from any directory. $PWD will have what you want.

This:

root@raja-H97-D3H:/home/raja# s1.sh

Would output /home/raja.

This:

root@pmt-H97-D3H:/home/pmt/tmp/p1/p2# s1.sh

Would output /home/pmt/tmp/p1/p2.

Also, you want to add the directory with the script to $PATH; not the script file itself. You should do this instead:

export PATH=$PATH:/home/raja/scps/shell
