Question

I am running linux 2.6. On bash shell, i would like to source a file. If i am in the current directory as the source file, then i can do

source abc.sh

But if i am on some other folder, i would so

source /path-to/abc.sh

I would like to capture whatever is typed after the command source on the command line in my script, So, for example, i want access to “abc.sh” and in the latter case, i want access to “/path-to/abc.sh” inside abc.sh

Thank you

You are looking for the $BASH_SOURCE variable which contains currently processed script.

For example if /tmp/a.sh is:

echo $BASH_SOURCE

Then:

$ cd /tmp
$ . a.sh
a.sh
$ . /tmp/a.sh
/tmp/a.sh
$ . ../tmp/a.sh
../tmp/a.sh

You can find more on it in info bash.
