I was about to post something similar to this last night, but thought I should look it up first. I knew that the FreeBSD.org web pages have links to on-line man pages for a whole host of versions of Unix, from V7 on. Lo: just about everyone has identical SIG numbers to V7, from 1 to 15. Just as you would expect. Things get a little weirder for the extended sigs above that. Solaris (SunOS5.7), for example, has 36 fixed-function signals and an indeterminate (varies at run-time) number of real-time signals. Then I looked at the RedHat 6.2 pages. Whew! Even some of the ones below 15 have weird meanings! All of the signals above 15 have two or three different encodings, depending on what platform you're using. That seems weird, but I guess that's a reflection of compatability with whatever the native version of Unix is on that platform. NetBSD is in the same position wrt multi-platform compatability, and their man pages simply don't include the signal numbers at all. They list the names, and refer to signal.h for the numbers. At least these ones seem to be universal: 1 HUP (hang up) 2 INT (interrupt) 3 QUIT (quit) 6 ABRT (abort) 9 KILL (non-catchable, non-ignorable kill) 14 ALRM (alarm clock) 15 TERM (software termination signal) Well, excluding plan-9, which doesn't seem to have the concept of a numbered signal. -- Andrew -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://slug.org.au/lists/listinfo/slug

You mean there is a Unix out there that doesn't have TERM on 15, or 2 on INT?

RE: [SLUG] Select and kill running process
'Course the original kill should've been call sig or something because that's all it really does - sends signals to processes, hence kill -9 123 is really kill -KILL 123 whereas kill -HUP 123 just sends the HUP signal to process 123. Actually signal 9 seems to be the only common signal number with the different Unixes. Better to use the signal name (eg HUP) than the number if you use different OSs during the day... Some of the GUI versions of process viewers can be fun, eg sun's sdtprocess where you can filter things out.

I remember the first time I used it on a Solaris box .. You should have seen the SURPRISE ON MY FACE the box (a REAL BIG server!!!) was shutting down and I couldnt do a THING to warn ALL the users on(connected to) that machine . It does make sense to have "killall squid" or "killall xterm" or something like that to have ALL processes by THAT name killed. But it does make sense to have "killall" as well. What surprised me that there was NO warning aka "Do you really want to do this". Nope. Nothing. Zilch. Zero. Null. The box just went blank (and so did my face). It is funny now, but not at that time. $grin$!

Re: [SLUG] Select and kill running process
This command is so dangerous if you work with other OS's... like Unixware, AIX, Solaris etc killall does that!! Kills all. ...including the process you wanted to kill in the first place :) This reminds me of answers to an editor quiz, assume vi without loss of generality. For each question, assume you begin at position 1 of line 1 Q1: How do you delete line 10 of the file? Answer: dG Q2: How do you delete line 15 through to line 20 of the file? Answer: dG ...and so it went on. >From the linux killall manpage KNOWN BUGS section: Be warned that typing killall name may not have the desired effect on non-Linux systems, especially when done by a privileged user. for large values of 'may not'! The choice of the name 'killall' for the Linux version was unfortunate. Maybe 'killbyname' would have been better (the original, natural kill could be aliased to 'killbynature'). I used to carry a shell script similar to the ps|awkish answers others have posted which I called 'namedkill' to kill processes by name not by process id.

Re: [SLUG] Select and kill running process
Slightly simplified version is:
ps -uaxw|grep process|awk '{print $2}'|xargs kill -9
(adjust $2 with regards to the args on ps)

Re: [SLUG] Select and kill running process
Hello Sluggers list process | grep desired-process | kill desired-process Can someone tell me the format of the last part? ps axf | grep process | kill -9 "process???" Others have presentented you with some clever shell/perl/awk/backtick ways of doing this. More convenient for me is a command called "killall" which does this stuff for you; it's part of a package called 'psmisc' on my system, psmisc also contains the useful fuser and pstree commands. $ killall netscape-communicator $ killall -9 netscape-communicator Hope this helps, Stuart. -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://slug.org.au/lists/listinfo/slug

If they are all 5 digit pids, you can use ps axf | grep process | cut -d' ' -f1 | xargs kill For 4 digit pids, you need to use -f2 in the cut.

RE: [SLUG] Select and kill running process
you can try
kill -9 `ps axf | grep process | awk '{print $}' `
