What scripting/programming languages are default on Mac OSX?

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.
