getting pwd of script
how can i get the absolute path of whatever directory a script and/or command is in when it is run?

i want to know the directory. say for instance, if i were to run the "who" command, i want to know exaclty where the who command is located.

if a user ran a script, i want to know where there script is located.

can this be done in a script?

shell: bash
os: linux / sunos

You can use pwd in the script to get the absolute path.

Code:
pwd

If you are looking for getting the absolute path for already running script, then you can try which <script name>. If it is located somewhere in the predefined path, then you will be able to see it. But this may not work.

Code:
which <script name>

dynamic variable PWD contains current directory:
Code:
$PWD
