THe actual User NAMES are numeric, or are you refering to each user's UID?

For example:

bladernr@klaatu:~/development/trunks/checkbox$ ps -U bladernr |head -5
PID TTY TIME CMD
334 ? 00:01:50 chrome
2375 ? 00:00:02 gnome-keyring-d
2384 ? 00:00:05 gnome-session
2430 ? 00:00:00 ssh-agent
bladernr@klaatu:~/development/trunks/checkbox$ ps -U 1000 |head -5
PID TTY TIME CMD
334 ? 00:01:50 chrome
2375 ? 00:00:02 gnome-keyring-d
2384 ? 00:00:05 gnome-session
2430 ? 00:00:00 ssh-agent

the first one uses my username, the second uses my UID... a 4 digit number.

If you have actual user names that are digits, that could be confusing
ps as it probably is expecting completely numeric strings to be UID
not usernames.

So, for example. lests say your sample name (that you provided) is
6545, and if you look through /etc/passwd, you see that hte UID for
user 6545 is actually 1002

if you ps -U 1002, you should get a process list for UID 1002, which
is the numeric for user name 6545. Does that makes sense?

So you could try something with the id command, like this:

bladernr@klaatu:~/development/trunks/checkbox$ ps -u `id -u bladernr` |head -5
PID TTY TIME CMD
334 ? 00:01:51 chrome
2375 ? 00:00:02 gnome-keyring-d
2384 ? 00:00:05 gnome-session
2430 ? 00:00:00 ssh-agent

that tells 'ps -u' to use the output of "id -u bladernr' ... the id
command returns the UID for username bladernr.
