Get snapshot of current processes

I just found out that all these years I’ve been using BSD syntax to call ps. There is also a “standard” syntax. The output is not identical but both give the information that I’m after most of the time…

“Standard” syntax

$ ps -ef

Where

• -e selects all processes
• -f shows “extended” information

BSD syntax

$ ps aux

Where

• a lift the BSD-style “only yourself” restriction
• u extra information?
• x lift the BSD-style “must have a tty” restriction

Musings

Why? Who knows…
