View 1 Repliesi was referring to an article given in following website.[URL] I was surprise to know that i can kill all running processes by using kill 0. However when i tried running the command nothing happened.
my machine details:
Code:

if i do a
ps aux | grep ftp
that would show me at least any active ftp connects started with the ftp command, right? Is there then a way to use that to somehow kill any stuck sessions that are older than an hour?
I am developing a daemon that is acting up and I am now unable to create any new processes (ie. I cannot start a new process to kill the other rogue processes). So, I need to be able to kill the processes from a remote machine. How do I do "kill" remotely without admin privileges? If I cannot kill my own process from a remote machine as a normal user then tell me so I can mark it as the correct answer.

There seem to be lots of patches and a couple of open bugs on this topic that have been there for about 10 years or so... Having convinced myself by googling that there is no easy solution, I'm now looking for a workaround of some sort. I'm writing a testing framework so the processes I'm running remotely could be anything at all, i.e. I only have control of the client side. Also the remote processes are of course highly unstable and I need to be able to terminate them if they hang. ssh -t won't work for me as I don't necessarily have a terminal. Finding the remote process ID would be enough so I can do ssh <machine> kill <pid>, but I don't see any way to do that either. Just using ps, pgrep etc seems to suffer from not being able to uniquely identify the correct process, and killing the wrong process is of course very bad.

This will get the TTY and idle time for all users.
For each idle time over a half hour, I do the following (TTY is the TTY from the previous command with a space.
I then kill those processes.
There must be a way to do this automatically in a bash or perl script. I've tried both, but can't seem to get things to work properly.
I'm attempting to use 'killall' to kill all mysql processes, however after using the command mysql processes are still alive. 'killall mysql' says no processes were killed, and while 'killall mysql_safe' gives no message there are still mysql processes alive afterwards.
Code:
# killall mysql
mysql: no process killed
# killall mysqld_safe

I don't know about your computer but when mine is working properly no process is sucking 95%+ over time. I would like to have some failsafe that kills any processes behaving like that. This comes to mind because when I woke up this morning my laptop had been crunching all night long on a stray chromium child process.
This can probably be done as a cron job, but before I make it a full time job creating something like this I'd thought I should check here. :) I hate reinventing the wheel.

View 1 Replies View RelatedI thought 'killall' would work, but I need to provide the "command" to kill. I'm really looking for a command that will kill all processes that have a particular file/directory open. Currently, my script fails on an 'umount' because there are several processes that have this filesystem open. The command 'lsof' is a good tool to determine which processes have a filesystem open, but I don't really want to write a script that parses through the 'lsof' output to capture PSIDs. Is there a linux command that can kill all processes that may have a particular filesystem open?

View 3 Replies View RelatedI have an issue on one of my servers whereby the [normally very helpful] du and tar programs are somehow using up too much or my system resources (du 40% mem, tar 20% mem) and causing problems. I am after a command which is able to kill a process without knowledge of a PID but by process name e.g. "du" and memory usage e.g. >= 10%.
Something along the lines of:
kill $(pgrep du) grep %MEM > 10
Although I know that is invalid syntax I cannot fathom the correct/best way to achieve this end!
I have my code with my fork in a server and each time a client connects one more process is created. i use this code for the handling of zombies
void sig_chld(int signo){//Diadikasia gia tin diagrafi twn 'zombies'

but i need the server to kill each zombie after the client is disconnecting and not to have to press ctrl+c
how to even start this Perl script. I have the following processes:

[code]....
I need a way to kill off the pids 2819, 2820 because they do not have a process tied to them like pids 2918, 2922 and 6657. The way it works is peek shell (pid 2918)is opened then it starts a ksh (pid 2922) session then from there the end user runs a command (pid 6657).
I'm trying to avoid kill -9 for the reasons described in the Useless Use of Kill -9 form letter. Is this function sufficient, or do I need to kill the kill processes after a timeout or take care of other subtleties?
soft_kill()
{
# Try to avoid forcing a kill
# @param $1: PID
kill $1 || kill -INT $1 || kill -HUP $1 ||
(echo "Could not kill $1" >&2; kill -KILL $1)
}
As an aside, what's a better name for this function? The current name reminds me of "Killing Me Softly", and manslaughter sounds a bit severe. Maybe spoon_kill (Google it)?

I'm working with Eclipse and it's starting to misbehave now and then which completely freezes my computer. Is there any emergency command to kill such a misbehaving process so I don't have to reboot my computer?
I already have a emergency xkill icon in my taskbar and a [Ctrl]+[F1] console with "> sudo killall eclipse" pretyped(!) but sometimes it's even to late for this. What I would need is a emergency command/console that gets a guaranteed amount of process time so I can kill these process.
User 1 and User 2 each start a mono process with sudo:
"sudo mono user1.exe" "sudo mono user2.exe"
Each user has a kill.sh in their directory, which is being called by user1.exe/user2.exe to kill the process.
The script itself is
ps aux | grep 'mono user1.exe' | awk '{print $1}' | xargs kill
which in theory should pull *only* the PID of "mono user1.exe" and kill only that. The problem: It kills any and every single instance of mono that is running on my system, every userx.exe thats open. I am confused, as a simple "ps aux | grep 'mono user1.exe'" does only return the mono user1.exe process and not the others. "ps aux | grep 'mono'" returns them all though. how I can modify that script so that it only kills the specific process? Would "pkill -9 -f 'mono MCuser1.exe'" work as well - or would it too kill every instance of mono? I cant do a lot more of trial and error, its not good I am killing those instances accidently...

the process is mcelog. When I do as root kill -9 2323 which is pid of mcelog the process is not killed. I tried doing the same from top, press K and enter pid of mcelog. doing ps auwx | grep mcelog I see there are several results. I tried killing all of them like kill -9 2355 2341 3425 2345. But re-running the above commands still shows them as running. How else would I troubleshoot this to avoid restarting of the box.
