Question

In a Windows command script, one can determine the directory path of the currently executing script using %~dp0. For example:

@echo Running from %~dp0 

What would be the equivalent in a Bash script?

Answer 1

For the relative path (i.e. the direct equivalent of Windows’ %~dp0):

MY_PATH="$(dirname -- "${BASH_SOURCE[0]}")" echo "$MY_PATH" 

For the absolute, normalized path:

MY_PATH="$(dirname -- "${BASH_SOURCE[0]}")"            # relative MY_PATH="$(cd -- "$MY_PATH" && pwd)"    # absolutized and normalized if [[ -z "$MY_PATH" ]] ; then   # error; for some reason, the path is not accessible   # to the script (e.g. permissions re-evaled after suid)   exit 1  # fail fi echo "$MY_PATH"
