What does ps command do, and what are the options e and f?
"man ps" will bring up the help (well, help as far as UNIX is concerned) page for ps, describe what it does, what arguments it can take, usage, and related commands.
As to roman33's question, is there Solaris for Windows? (say no). If someone is talking about AIX, HP, or Solaris, you can pretty much count on the OS being UNIX.
