Get directory that script was called from

Question

I have a script doSmth in /usr/bin. Is it possible to print the directory the script was called from is printed out by the script?

So If I call doSmth from /home/me the output will be /home/me.

Answer 1

When you invoke a command in the shell, the new process inherits the working directory of the parent. Here are two ways get the working directory:

echo "$PWD" # variable
pwd         # builtin command

Answer 2

By "directory it was called from" you seem to mean its working directory. You can change this inside the script using e.g., cd, but before you do so, pwd will print it out. It'll also likely be in the variable $PWD

If you'll need the initial working directory after changing it, just save it at the top of your script (before changing it)

#!/bin/bash
initial_wd=`pwd`

# ... do a lot of stuff ...
# ⋮

cd "$initial_wd"

If you're using this to get back to the directory you started in, see also pushd and popd.
