I was wondering what programming or scripting languages come pre-installed on OSX? Particularly programs that can be run from the command line.

I'm planning on parsing some CSS, and outputting an html page. I've done it in python before, but I would like to make sure it's transferrable to others in my organization.

OS X doesn't come with any compilers built-in. It has a number of scripting languages though:

  • Python (2.7.2)
  • Perl (5.12.4)
  • Ruby (1.8.7p358)
  • PHP (5.3.15)
  • Bash (3.2)
  • Zsh (4.3.11)
  • AWK
  • Tcl/Tk (8.5.9 and 8.4.19)

The listed versions are included in OS X Mountain Lion (v10.8), but some version of each of these has been included in OS X since at least v10.3.
