ps syntax

I just noticed this morning that the newest version of ps, in procps 2.0.7, supports both the standard and BSD format for the command. Personally, I've grown up using ps -ef, which I like because it lists both the pid and ppid of a process. I know that the older version ps al gave generally the same thing, it always tripped me up jumping from HPUX to Linux and back again. Just an observation. -mk

If it ain't broke, fix it till it is.

i don´t know what version of ps i have, but to me ´ps´ is the same as ´ps -aux´; ´ps´ alone is too poor, it not displays any information.

Solaris provides both formats. The standard ps command located in /usr/bin and the BSD ps command located in /usr/ucb directory.
