Kill PID question...

Ok, I've had a look around, and can't seem to find anything other than the normal man pages (like at http://unixhelp.ed.ac.uk/CGI/man-cgi?kill). Does anyone know how to kill more than one process at a time?

maybe something like;

kill 1234,2323,4343,3343

Any feedback wouldbe great. I got 20 processes i gotta kill, and doing each one seperatly will just be a pain in the arse Tongue

Thanks

20 processes to kill?

Yikes...are you sure?

>>can't seem to find anything other than the normal man pages<<

It tells you on the very first line.

>>
Specify the list of processes that kill should signal. Each pid can be one of four things. A process
name in which case processes called that will be signaled. n where n is larger than 0. The process
with pid n will be signaled. -1 in which case all processes from MAX_INT to 2 will be signaled, as
allowed by the issuing user. -n where n is larger than 1, in which case processes in process group n
are signaled. IFF a negative argument is given the signal must be specified first, otherwise it will be
taken as the signal to send.

Lol..that doesn't help Tongue

You have to remember I've only been using servers for just over a month...unlike you who has been using it for over a year (?).

Yeah, I'm sure there are over 20 processes i gotta cancel. Heres a small outtake of 'ps aux';

You don't know what a list is?

I know what a list is...but when I type in "kill 1234,12334,232" it doesn't work! Says the process ID is not recognised!

Re: [AndyNewby] Kill PID question... In reply to

I think you'd be much better off finding the route cause of this probkem. What's going on here? You're firsing off programs via CRON that don't exit properly and send themselves into infinite loops? How does your server cope with the memory usage?

Re: [Wil] Kill PID question... In reply to

Its not as bad as it looks. I set up the cron job, but put it to run every 12 minutes, instead of hours Tongue

I'm gonna edit the cron file as soon as I can stop enough of the files from running and bogging down the server. I've also changed the name of the file that is running, in a hope that no new copies will now get started Smile

Thanks

Just do a killall perl and a killall /usr/bin/sendmail (then restart sendmail). Of course this won't work if you have other perl or sendmail processes running that you don't want killed.

Re: [brewt] Kill PID question... In reply to

Darn. The 'killall /usr/sbin/sendmail' command worked, but doing 'killall perl' doesn't seem to. It looks like the command was executed (no error message), but none of the processes are actually stopped!

Any ideas? Does it matter who I am logged in with for my telnet session?

Also, anyone know why I'm getting loads of copies of httpd running?
