how do I display the user of a process using ps?

Hi all when I run

Code:

ps -A

I get a list of PIDs and names but not the user they belong to. the -u option seems to mention users and

Code:

ps -u

prints processes owned by my current user, but I'd like to display ALL users and

Code:

 ps -Au

gives me an error. I was wondering if this is possible? and if so, what's the syntax. The man page is entirely unhelpful.

Thanks for the help!

uyyy never mind...i figured it out after some more trial/error

Code:

ps -A u

works
I guess you need a space and no dash in front of the lowercase 'u' to get it to work.

does ps - aux works on slackware?

yeah it does...Thanks for the help!

it doesn't work with the space between the ps and the - but either
ps -aux
or
ps aux without the - work well. Apparently according to the ps man page ps -aux is not the same as ps aux. Apparently, ps -aux interprets that it should list the processes for user x instead of ps aux which should list processes for all users.

This is one part of linux I feel that I'll never understand. How to pass command line options. I get it when they're complete like --user=<something> --this-does-something-else --this-does-another

but when they're just single letters some programs let you do them without a - like tar and some require a - and the most frustrating is when (like ps) each letter means something different if the - is present or not.
