How to terminate the execution of a process after some time in Linux
Suppose that you have to execute a Java program which is fairly unstable and sometimes hangs on and never terminates. Is there a simple way to make it terminate (actually by killing the process) after some time? Yes, of course. There is always a way for such things. Ways for everything do not exist though.
So, let's say you have a program.jar to execute but you want to kill its process after 5 minutes in case it does not terminate. A very easy way to do this is the following:
#!/bin/bash # here you set the time you want to wait before killing the process time=5m # then you run your program in the background java -jar program.jar & # you are waiting for the time you have set sleep $time # some printing - for fun termination="\nTerminating the process...!!\n" echo -e $termination # and now you are about to kill it kill %1
You can create a script.sh file, just copy paste the code above, and then run the script.sh file (by using the command > sh script.sh).
