Get absolut path to your bash-script

Another way of doing it that's a bit clearer. I'm a fan of readable code.


There are 2 alternatives - vote for the best!

Terminal - Alternatives
PATH=$(cd ${0%/*}; pwd)

what is the point of this command?

Comment by syssyphus 345 weeks and 4 days ago

Within a shell script you might need to work out where the script itself is located. For example if you had a script called myscript.sh and a config file called myscript.cfg in the same directory you might need to work out the full path to the config file. Using $(dirname $0) won't always give you the full path. It will provide the path that the script was executed with. This might be a relative path e.g. ../somedir/myscript.sh. The command would resolve that to /full/path/to/somedir/myscript.sh.

Hope my ramblings make sense.
