    If this returns nothing does that mean I don't have access to translate the id to a username? Commented Apr 17, 2012 at 4:07

    More likely you didnt set "$uid"` or that uid doesn't exist. Does grep ":$uid:" /etc/passwd find it? Does getent passwd produce any output? Commented Apr 17, 2012 at 4:14
  • @cwd: You should always have access to translate an id to a username. For instance, ls -l is always doing this. Commented Apr 17, 2012 at 7:00
  • Just curious because looking at an ls listing on a shared host was showing numbers in the user / group name columns with ls. Perhaps it is a security precaution or jailshell thing? Commented Apr 17, 2012 at 19:50
  • @cwd More likely the shared host is using an /etc/passwd mounted / shared from elsewhere which wasn't mounted at the time. Commented Apr 17, 2012 at 19:56
