[Resolu]Aide pour ps f et ps u

Bonjour,
Salut j'aimerai que vous m'expliquiez ce que signifie ces mots

[chabanus@localhost ~]$ ps f

PID TTY STAT TIME COMMAND
5596 pts/5 Ss 0:00 /bin/bash
5638 pts/5 R+ 0:00 \_ ps f
5532 pts/3 Ss 0:00 /bin/bash
5590 pts/3 S+ 0:00 \_ ./a.out
5591 pts/3 Z+ 0:00 \_ [a.out] <defunct>
5592 pts/3 Z+ 0:00 \_ [a.out] <defunct>
5593 pts/3 Z+ 0:00 \_ [a.out] <defunct>
5594 pts/3 Z+ 0:00 \_ [a.out] <defunct>
5443 pts/2 Ss+ 0:00 /bin/bash

PID,TTY,STAT,TIME COMMAND ?

Ainsi que:

USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
chabanus 5443 0.0 0.1 4156 1868 pts/2 Ss+ 17:19 0:00 /bin/bash
chabanus 5532 0.0 0.1 4156 1876 pts/3 Ss 17:20 0:00 /bin/bash
chabanus 5590 0.0 0.0 1420 400 pts/3 S+ 17:21 0:00 ./a.out

chabanus 5640 0.0 0.0 2308 904 pts/5 R+ 17:21 0:00 ps u
