How to get absolute path name of shell script on MacOS?

Question

readlink -f does not exist on MacOS. The only working solution for Mac OS I managed to find on the net goes like this:

if [[ $(echo $0 | awk '/^\//') == $0 ]]; then     ABSPATH=$(dirname $0) else     ABSPATH=$PWD/$(dirname $0) fi 

Can anyone suggest anything more elegant to this seemingly trivial task?

Answer 1

Another (also rather ugly) option:

ABSPATH=$(cd "$(dirname "$0")"; pwd -P) 

From pwd man page,

-P      Display the physical current working directory (all symbolic links resolved).
