Oh, the age old question of what's your favorite programming language.

With the years it has come to whatever does the trick the quickest and without too much hassle.
Sometimes it's a simple shell script, sometimes it's Perl, sometimes it's Python, sometimes it's C, sometimes it's C++, sometimes it's Java. I alternate between them depending on the scenario.
I have favorites but they are for specific tasks and not for generic *nix programming.
Now if you asked me what syntax or ideologies of programming I liked better and which language would fit that then I would also say that it depends on what I'm trying to do.

TLDR: Whatever works works.
