Can I get the absolute path to the current script in KornShell?

Question

Is it possible to find out the full path to the script that is currently executing in KornShell (ksh)?

i.e. if my script is in /opt/scripts/myscript.ksh

Answer 1

How the script was called is stored in the variable $0. You can use readlink to get the absolute file name:

readlink -f "$0"
