This happens:
# ps -ef
oracle 31868 1 0 08:37 x y z 00:00:00 ora_p103_salerep
103 1789 1788 0 08:39 pts/2 00:00:00 -bash
103 2099 1789 0 08:39 pts/2 00:00:00 ps -ef
103 2100 1789 0 08:39 pts/2 00:00:00 grep -i 103
Notice we see “103″ in the first column instead of the username, this is because uid 103 is “siebadmin”, which
is >8 characters long. Ps has a column width of 8 on the first column, and if the username does not fit, it uses
the uid. This is not fixable, unless in source.
