Get location of "source"ed script

I want to execute statements like (shell is bash)

/# source /workspace/scripts/script.sh
/workspace/scripts# source script.sh

Inside the script.sh I want to get its own location. (script.sh wont be in the PATH variable)

I could do this using readlink -f $0 when run the script, but the same doesnt work when I source it.

I dont want the solution to be dependent on where I run the source command from. (otherwise pwd would have been enough)

Is this possible?

Since script.sh is in your path, you should be able to get it's full path using which. So, in the script, if $0 isn't a full path, you can do which $0.

carabiner$ cat ~/bin/test.sh
#!/bin/sh

echo test - $0 $1
which $0

carabiner$ source test.sh
test - test.sh
test.sh is /home/zigdon/bin/test.sh

It is not possible to find the location reliably in 100% of all cases.
If you use bash your best bet is $BASH_SOURCE variable.
This link is very helpful on this topic.
