To compare two strings in a bash script, you will have a snippet of code similar to the following:
if [[ $(pwd) == "/path/to/current/directory" ]] then echo "You are in that directory"; fi
You may only want to do a partial string match. For this, you can use the
* wildcard symbol.
if [[ $(pwd) == *"directory"* ]] then echo "You are in that directory"; fi
