Hi Jozef

I tried your command but it prints all processes not the grep processes.

Or simply

ps -fp PID1,PID2

Note: use the comma as a separator between the PID numbers, not spaces.

Hi John,

#ps -ef |egrep '(PID1|PID2)'

or

#ps -fp PID1,PID2
Best wishes,

Re: How to get status of 2 process only

Hello John,

that's strange. I tried to grep for diag and bash processes and it works:

root@vl1:(/)#ps -ef | grep -e diag -e bash
root 2147 2128 0 22:39:49 console 0:00 bash
root 1712 1 0 22:39:06 ? 0:01 /usr/sbin/stm/uut/bin/sys/diagmond
root 2494 1712 0 22:49:36 ? 0:00 diaglogd
root 25575 25278 0 13:46:59 pts/0 0:00 grep -e diag -e bash
novakj 25242 25240 0 13:34:34 pts/0 0:00 -bash
root 25278 25262 0 13:34:40 pts/0 0:00 bash

Re: How to get status of 2 process only

Hi,

I tried ps -fp PID1,PID2 it works fine, but also i need to use by process name as process id could be changed. so could you provide me command to check process with 2 or 3 process names, not ID?

Hi John:

> so could you provide me command to check process with 2 or 3 process names, not ID?

Dennis already pointed you in the direction you need --- finding a process _by_name_ without using 'grep'. For example:


# UNIX95= ps -C cron -C syslogd -o pid= -o comm=

...would find and list the pid and the name of the processes named "cron" and "syslogd".

The equal symbol following the 'ps' field name suppresses the heading. The '-C name' switch/argument is valid only when the UNIX95 variable is set. Writing 'UNIX95= ' with whitespace before the command that follows, _without_ any semicolon, sets the variarble only for the duration of the command line. You don't want it capriciously set in your environment as it impacts the behavior of many commands in subtle ways.

Dennis prefers to write something like 'UNIX95=EXTENDED_PS' which could just as well be 'UNIX95=1' _but_ not 'UNIX95=0' as you might infer would turn it _off_. ANY lvalue use of UNIX95 will turn it _on_. Beware.
