Lazyweb request: how to find full path to script

Friday, 4 July 2008

Dear Lazyweb,

this is something that I searched for quite some time and could not find yet, maybe a helpful soul knows.

In a bourne shell script, how can I find the full path of the script being executed?

Thanks in advance.

Update: the following command, sent by Celso Pinto, passes all my tests.

SCRIPTDIR="cd $(dirname $0);pwd

For the record, I used two scripts to test this. First, the script_dir.sh script:

#!/bin/sh
echo "\$0 is $0"
SCRIPTDIR=dirname $0
echo " dir: $SCRIPTDIR"
SCRIPTDIR="cd $(dirname $0);pwd"
echo " dir: $SCRIPTDIR"

The script to run the tests, run_script_dir_tests.sh:

#!/bin/sh chmod 755 script_dir.sh ./script_dir.sh 1 ../$USER/script_dir.sh 2 ../$USER/bin/../script_dir.sh 3 sh ./script_dir.sh 1 with sh sh ../$USER/script_dir.sh 2 with sh sh ../$USEr/bin/../script_dir.sh 3 with sh export PATH=pwd:$PATH

cd / script_dir.sh "via path"
