How to stop specific map by crontab

[LawOutLaw]

Hello everyone.

I am sorry if such question has been posted here earlier, but i couldn't find any similar.

So, as we know not all maps are useful during whole week. One of such maps for example is is12 (Forest Ruins). And I need to start it at 15:00 of Sunday and stop it at 18:00 without pwAdmin but using cron.

I created bash script for starting

startIS12.sh:

#!/bin/sh

PW_PATH=/PWServer

cd $PW_PATH/gamed; ./gs is12 >$PW_PATH/logs/game_all.log &

Then wrote in crontab this

crontab:

00 15 * * 0  root    /etc/cron.pw/startIS12.sh
00 18 * * 0  root    /etc/cron.pw/stopIS12.sh

And here I need in bash script for stop this map at 18:00 Sun as in crontab

Something like this

stopIS12.sh:

#!/bin/sh

ps a | grep is12

Get the id number from that list// how to get this ID by script?

kill -9 idnumber //and how to insert found ID here?

Please help with stop[map].sh script

heh, I needed something just like this a few days ago because Java is an asshole to start in init

kill -9 $(ps aux | grep "java -jar JTS3ServerMod.jar" | grep -v grep | cut -c10-15)

replace the INSIDE of the quotation marks with command used to start process

But that is only if you have absolutely no way of knowing what the process ID is when you start it

You can modify the start script to do this

#!/bin/sh

PW_PATH=/PWServer
PID_PATH=$PW_PATH/pids
#                            >> means append, > means overwrite
cd $PW_PATH/gamed; ./gs is12 >> $PW_PATH/logs/game_all.log &
#    $! contains the process ID of the last command run by user using it
echo $! > $PID_PATH/is12.pid

And for the kill script you could then use that pid file to do this

#!/bin/sh
PID_PATH=/PWServer/pids

kill -9 $(cat is12.pid)

btw using $() is basically an anonymous function in bash, whatever comes out of the stdout in the end is the return value.

Thanks a lot. I'll try it now :)

Like this?

kill -9 $(ps aux | grep "./gs is12" | grep -v grep | cut -c10-15)

Yes that would work, but see above as I edited post with a better method...

Just first method is more useful for me in my opinion. Coz um using pwAdmin for start server and run all maps. And I don't know how to edit .jsp files containing commands which start and stop maps manually through pwAdmin. In such cases when I started specific map by pwAdmin I'll not be able to control which ID by creating pid files

This is my method:

#!/bin/sh
/bin/kill -9 `ps -ef | grep is12 | grep -v grep | awk '{print $2}'`

And it works perfectly... I never got any issues since few months now.

[tbnanubis]

kill -9 `ps -x | grep is12 | grep -v grep | awk '{print $1}'`

edit: ah damn thats the same romulan's version does, except with -x its the first column to select

side note: awk, as well as gawk and sed are nice little command line tools that can do awsome stuff (awk is a small but turing-complete programming language).. get used to it and they are very helpful ;)

And don't forget pkill(1)...

Just be careful with it, since it's fairly indiscriminate. 'pkill a' will kill EVERYTHING running (that the current UID can kill, of course) with the letter "a" in its process name.

man pkill
