that's not so simple. even "compatible" options may differ in their
output or whatever. let's try -j, -l, and -u.
$ ps -j
USER PID PPID PGID SESS JOBC STAT TT TIME COMMAND
root 1326 1 74 c0efca80 0 I p0- 0:00.22 /bin/sh /etc/rc.local.n
e
$ ps -l
UID PID PPID CPU PRI NI VSZ RSS WCHAN STAT TT TIME COMMAND
0 1326 1 16 10 0 712 304 wait I p0- 0:00.22 /bin/sh /etc
$ ps -u
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
root 16604 0.0 0.5 804 572 v1 R+ 5:15AM 0:00.00 -ksh (ksh)
$ ps5 -j
ps5: sid: keyword not found
PID PGID TT TIME COMMAND
1326 74 p0- 00:00:00 sh
(oop! incomplete work, sid is missing, forgot about that)
$ ps5 -l
F S UID PID PPID C PRI NI ADDR VSZ WCHAN TT TIME COMMAND
86 I 0 1326 1 0 32 0 c84c6ba0 712 wait p0- 00:00:00 sh
$ ps5 -u
(different meaning)
also, the current ps(1) implementation is a lot ugly when combining
format options, let's try -lu :
$ ps -lu
UID PID PPID CPU PRI NI VSZ RSS WCHAN STAT TT TIME COMMAND
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
0 16635 8064 1 28 0 236 104 - R+ v1 0:00.01 head -2
root 16635 0.0 0.1 236 104 v1 R+ 5:20AM 0:00.01 head -2
compared to :
$ ps -Blu
USER UID PID PPID CPU PRI NI %CPU %MEM VSZ RSS WCHAN TT STAT START
ED TIME COMMAND
root 0 16636 8064 2 28 0 0.0 0.3 504 332 - v1 R+ 5:21
AM 0:00.00 ps5 -Blu
-B stands for BSD ps(1) option treatment. see my previous post about that.
