I have some runnable-jar files. I want to run them at regular intervals and also kill those processes after some time. I am a newbie when it comes to Ubuntu or linux in general. Can anybody suggest me the best practice to achieve it?
Use something like
#!/bin/bash
java -jar <name-of-the-jar-file> &
javapid=$!
sleep <some-time-in-seconds>
kill $javapid
in a file, make it executable (chmod +x ) and run it using
./<filename>
This will start the jar-file and kill it after some time. There are several ways to excecute the command at regular intervals. You could use cron ( http://help.ubuntu.com/community/CronHowto ) to always excecut it as long the computer is runnig. Or use a simple shell script loop to start the execution from the command line:
#!/bin/bash
COUNTER=0
while [ $COUNTER -lt 100 ]; do
<same as above without the first line>
let COUNTER=COUNTER+1
done
This will run the command 100 times, you could stop the execution simply by pressing ctrl-c.
