macos - Bash script absolute path with OS X

Question

I am trying to obtain the absolute path to the currently running script on OS X.

I saw many replies going for readlink -f $0. However since OS X's readlink is the same as BSD's, it just doesn't work (it works with GNU's version).

Is there an out-of-the-box solution to this?

Answer 1

These three simple steps are going to solve this and many other OS X issues:

1. Install Homebrew
2. brew install coreutils
3. grealpath .

(3) may be changed to just realpath, see (2) output
