[[ps]] will show your running processes. If run from a regular user shell or an xterm window, it'll only show you '''your''' processes. If run as root, it will show ''all'' processes.

There were different switches used in different versions of [[ps]] -- historically, [[SysV]] needs the '''-ef''' switches to show all processes and [[BSD]] needed '''-aux'''. [[ps]] is now smarter and will accept either switch and show you what you wanted to see.

+[[BSD]] does not support the switches (options) defined by the [[UNIX]] standard because historical BSD implementations assigned conflicting meanings to these switches. Enhancements commonly found on [[Linux]] and [[Solaris]] are likewise unavailable. Near-equivalent common options are as follows:
 ==Common flags==
- -a all users, not just the user running the [[ps]] command
+;a: all users, not just the user running the [[ps]] command
- -u show system info on commands (user, pid, cpu% etc)
+;u: show system info on commands (user, pid, cpu% etc)
- -c show the command only, not the path to it
+;c: show the command only, not the path to it
- -x show processes that don't have a terminal controlling them
+;x: show processes that don't have a terminal controlling them
- -r sort by CPU use
+;r: sort by CPU use
- -w wide output
+;w: wide output
