UNIX for Dummies Questions & Answers

I am new to the Unix.
Can someone tell me what is the difference between 'PS' command and 'PS -aux"?
Isn't 'PS' mean the current running process?
Isn't 'PS -aux' mean the current running process too?
If they are the same, how come 'PS -aux' always has a lot more listing than 'PS'?


Thanks,

Code:

ps -a

selects all processes except: those not associated with a process - things like daemons, and process leaders.

-e all processes

try reading the output from this command

Code:

man ps

The -x option gives you the FULL command listing...sometimes it can be several lines long.

Without it you only get 80 chars...


Here is a REAL example.


# ps -aex |grep 23052
23052 ? 1:00 FNDLIBR FND Concurrent_Processor MANAGE OLOGIN="APPS/A591A
0917583869700000000000000000000000000000000000000000000" QAPPL="SWAP" QUEUE="PAY
MENT_MANAGER" PMONMETH="LOCK" DECRYPT=Y TARGET="CHTCFAS1" CPID="203318"
26935 pts/tb 0:00 grep 23052


# ps -ae |grep 23052
23052 ? 1:00 FNDLIBR



Notice a difference?

What option can be used for this same result on Solaris ?
It does not have x option so ps -aex does not work.
Any ideas will be highly appreciated.

Solaris does support the x option, you're just not using the right ps to get it to work, you need the berkley version; use /usr/ucb/ps and you'll be able to use the x option.
