Telling where the script is

[peterneve]

Hi,

I have a script which greps itself. This work great when the user is in the same directory, but falls down when run from a different folder. How can I get the script to find where it actually is (not where the user is)?

Thanks,

If $0 don't hold the full pathname you may try to play with the type builtin or alias.

Hope This Helps, PH.

You check the $PWD enviroment varible...

If you only have one instance of your script, it can be found by:

whereis myscript

but manuals, rc-files, ... are found to.
So use which:

which myscript

If the user calls it with full path, and it isn't in THE path, or another version is found earlier in the path, which will not work correctly.

fullPath=$(whence $0)

[predamarcel]

to get the absolute path, in bash

#!/usr/sbin/bash
SCRIPTSELF=$0
FIRST_CHAR=${SCRIPTSELF:0:1}
if [[ '/' == $FIRST_CHAR ]]
then
        echo $0
else
        echo $PWD/$0
fi

and the output:

l1000db2 # /tmp/get_myself.sh
/tmp/get_myself.sh
l1000db2 # cd /tmp
l1000db2 # ./get_myself.sh
/tmp/./get_myself.sh
