Shell Scripting – How to Detect the Current Directory

In Bash, you should get what you need like this:

#!/usr/bin/env bash

BASEDIR=$(dirname "$0")
echo "$BASEDIR"

As already mentioned, the location will be where the script was called from. If you wish to have the script reference it's installed location, it's quite simple. Below is a snippet that will print the PWD and the installed directory:

#!/bin/bash
echo "Script executed from: ${PWD}"

BASEDIR=$(dirname $0)
echo "Script location: ${BASEDIR}"
