I tried these, all without success:

  • ps --version
  • ps -version
  • ps -v
  • ps -V
  • man ps, searching for version information

Specs:

  • Mac OS X 10.8.2
  • MacBook Pro 2009

I was able to find PS(1) in the man page, but I'm not sure that this provides sufficient version information for a bug report I'm making to Apple. –  mcandre Oct 1 '12 at 18:08

ps is part of the Mac OS X core distribution and released as open source by Apple. It is part of the adv_cmds package and has no version number on its own.

Unless you installed a custom ps, you can identify it by providing your OS X version number, or the version of the adv_cmds package on http://www.opensource.apple.com corresponding to your OS X version, e.g. version/release 149 for OS X 10.8.2.

It looks like it doesn't want to tell its version. The best I can up with is strings -a $(which ps). You'll find out that it is the FreeBSD version, mine says ps.c,v 1.110 2005/02/09.
