If you're a #Linux person and using the command "ps" with options like "aux" instead of e.g. "-e" (i.e. options without leading "-"), you likely learned the #Unix #commandline on #BSD or maybe SunOS 🧔. (Or by someone who grew up with them. 🙂)
In other news: #TIL that (in either variant) the option "j" (e.g. as "ps ajx" or "ps -ej") also shows the PPID (parent PID, only with BSD style options), PGID (process group ID) und SID (session ID).
@sej7278: According to the man page of ps:
To see every process on the system using standard syntax:
ps -e
ps -ef
ps -eF
ps -ely
To see every process on the system using BSD syntax:
ps ax
ps axu
@sej7278: Debian Unstable in my case. ps(1) is in the procps package, i.e. not debian-specific.
And ps(1posix) (Debian package manpages-posix) only describes the options starting with a single "-" ("ps -ef" etc.)
I vaguely remember that I used "ps aux" already on SunOS (which was my first contact with Unix) as well as on FreeBSD (which I administrated for a while between 2003-ish and roughly the 2010s.
SunOS was more BSD like while Solaris was more SysV-like, so maybe I should remove Solaris.
@mirabilos @sej7278: The longer the more I think so. I removed "Solaris" from the original text.
I mostly used SunOS and used Solaris only for a short time at the very end of my studies and always found it rather odd compared to SunOS, NetBSD and Linux back then.
