ps command gives only userid for certain users, not username

This is driving me crazy. I've added two users today with "useradd -m <username>". All processes for the first user I added show up in "ps -elf" with the userid listed instead of the username. Processes for the second user show up as I would expect: with the username.

For the problematic user, when I do ps -eo "%u", the list includes the username but doing ps -eo "%u %c" causes it to display the userid with the command.

The entries in /etc/passwd and /etc/shadow seem right.

On my various boxes the full text field selectors seem the most reliable, e.g.:

Code:

> ps -eo "ruid ruser cpu %cpu"



  305 tegner    0  0.0

    0 root      0  0.4

    0 root      0  1.6

The full text versions are in the man page, have fun.

How does

Code:

ps aux

work for you?

Actually, the 'ps -eo "ruid ruser cpu %cpu" ' command still gives me just the uid #, like this:

[root@zen init.d]# ps -eo "ruid ruser cpu %cpu"
RUID RUSER CPU %CPU

(edited slightly to pull most root entries for easier reading).

The "ps aux" command gives the uid as well.
