Package: procps
Version: 2:3.3.15-2
Severity: minor
File: /bin/ps
Dear Maintainer,
the 'man ps' page says
*********************
Note that "ps -aux" is distinct from "ps aux". The POSIX and UNIX
standards require that "ps -aux" print all processes owned
by a user
named "x", as well as printing all processes that
would be selected by
the -a option. If the user named "x" does not
exist, this ps may
interpret the command as "ps aux"
instead and print a warning. This
behavior is intended to aid in
transitioning old scripts and
habits.
It is fragile, subject to
change, and thus should
not be relied upon.
***********************
I created a user with the name 'x'. It didn't make any difference
between 'ps aux' and 'ps -aux'.
Did the behavior change? Is the man page out of date? Or did I
misinterpret the behavior.
Greetings
Tobias

No, it's still an issue, at least in procps 4.0.4
$ id x
uid=1004(x) gid=1004(x) groups=1004(x),100(users)
$ ps aux | wc
378 4685 39719
$ ps -aux | wc
8 32 251
$ ps -a | wc
8 32 251
(delete user)
$ id x
id: ‘x’: no such user
$ ps -aux | wc
378 4685 39714
So with user 'x' present, ps interprets it: all processes with a
terminal PLUS all processes run with user x.
User x was running no processes, and there were 8 with a terminal.
That's what the manpage is warning about. I'm not sure why you didn't see this.
