Shell Programming and Scripting

Here is an old thread about this subject.

$PWD won;t work. That would give me the directory from where I am executing the script, not where the script is.

could you

Code:

ps -ef | grep my_script

from within your script?

Please read my response. If $0 contains a relative path, it is relative to $PWD!

For example, if the user's working directory is /home/foo and he runs the script (/home/bar/x) by typing "../bar/x" (which is what bash, at least, gives in $0), we combine $PWD and $0 to get "/home/foo/../bar/x" which is an absolute path to the script. Yes, the up and down with ".." is ugly, but it works.

The script supplied by DoxieLvr has some errors. Try...

Code:

#!/bin/bash
if [ "${0:0:1}" = "/" ]; then
    spath="$0"
else
    spath="$PWD/$0"
fi
spath=$(dirname "$spath")
echo "Script is at $spath"

For a script that can be executed by multiple users, I'm assuming that it exists in a directory that's contained within the PATH.

dirname `which script.ksh`

Hope this helps!

Post #6 indicates that 'which' can not be used. DoxieLvr's script with my corrections will provide the correct path to the script.
