BASH script, get the script directory

Hello!

I am running a shell script from within another shell script. They are in different directories and wanted to know the best way to get the current directory that the sub shell script is running from.

I've tried using:
$(dirname $0)
PWD

But those show the location of the original shell script. Every command seems to act as if it is in the original shell script.

I am calling the second shell script from the first using the '.' dot command. Any advice is appreciated.

thanks!

If you do not have cd or chdir within the scripts, the directory would reflect directory (cwd) from when the script was started.
Since the scripts seem to be running without an issue, it sounds as though explicit and full paths are being used.

omarfarid

as mentioned by arnold the current working directory or the present working directory will not change unless you change it! If you want the location of the script called then it will be the current directory plus the relative path to the script or if the script is in the set PATH then the command

basedir `which command`

OR

basedir which scriptname`

should give the dir name in which the command or script is in.

typo

basedir `which scriptname`
