Re: Determining the current path of a sourced script

Ben,

Thanks for your response.

Succint reply: No, that doesn't work.

Verbose reply:
PWD gives me the path to the current working directory of the process
which called the script. When initializing bash (e.g. when logging
in), which is the most common time one's $HOME/.bashrc is executed,
the current working directory is $HOME. So, in this instance, $PWD ==
$HOME inside /devel/bashrc when it is sourced by $HOME/.bashrc. I need
for /devel/bashrc to magically detect that it is in /devel (or
wherever the evil user has placed it).

I need something like __FILE__ in C.

All I can think to do, since the user has to modify their .bashrc
anyway (to source my bashrc), is to force the user to also export an
environment variable indicating where they placed my bashrc. I don't
want to tell the user to edit my bashrc, because then they will be
tempted to muck with everything else in there.

A programmer's life would be much simpler if there were no users.

Cheers,
Tony
