[[!meta title="Is language "foo" or software package "bar" installed?"]]
If you’d like to check whether the service has certain software
installed, you can [ssh to scripts.mit.edu](/faq/41) from an Athena
computer (you must first have signed up for one of the script
services).

The service supports essentially any programming language with a
Linux implementation. If you want to use a language (or language
version) that is not installed on the server, you can either
contact us at scripts@mit.edu (we might be able to install what you
want) or you can use a
[shebang line](http://en.wikipedia.org/wiki/Shebang_(Unix)) (and
provide your own binary in AFS). Since the server is running Linux,
custom shebang lines must point to Linux-compatible executables.

Here’s a shebang line demo:

We also have instructions for
[installing Python libraries into your locker](/faq/126/).
