It's okay, I found out: `$newname = getpwuid($uid); print "newname: $newname";` [download] Works too. :D Peter	[reply] [d/l]

Given the number 32149, who can convert this back to the username ? 1. Obviously I can, as I'm the user and it works okay. 2. Hopefully the 'sysadmin' can. 3. What about other users on the same server ? 4. Can anyone else convert the number back to the username ? Peter	[reply]

Yes Yes Yes Yes* * But they would probably have to hack it. Try this (the $ is the system prompt): `$ grep 3214 /etc/passwd \| head` [download] This will show you the usernames/UID/GUIDs of all the users on your system (with a UID/GUID that m/3214/ to limit the result set as you have 32K users on that box) cheers tachyon	[reply] [d/l]

The best answer of course, is "Try it and see". On my box at least, any user can get the user name back from the uid. There might be ways to prevent this, but I'm not sure if that would break other stuff.	[reply]
