I have to execute a java application on a remote server through command line.

I normally run the application like:

java -jar /home/user/files/simulator.jar -nogui:/home/user/files/my-sims/sim1.csc

this prints in my terminal a lot of compilation outputs, and during the simulation it prints the simulation time remaining every 1% increase of the simulation progress.

Obviously, during the simulation the terminal is unusable due to these outputs.

I tried to run the application with a & at the end to run it in background, like:

java -jar /home/user/files/simulator.jar -nogui:/home/user/files/my-sims/sim1.csc &

but the compilation outputs are printed anyway, so I cannot use the terminal to logout from the server.

How can I solve?

Thanks

  • what about piping the output to /dev/null? java -jar ... 2>&/dev/null Commented May 17, 2013 at 17:42

On linux, direct the output to /dev/null

java -jar /home/user/files/simulator.jar -nogui:/home/user/files/my-sims/sim1.csc > /dev/null

To skip the errors on consol, add an &

java -jar /home/user/files/simulator.jar -nogui:/home/user/files/my-sims/sim1.csc &> /dev/null

The answer is borrowed from serverfault.

@aliants: What do you mean by terminal locked? Are the outputs still printed?
It doesn't return to user@user-VPCEB4B4E but it remains the rectangular character blinking (sorry for my bad explanation but I'm not able to tell it in english).
Ok, I solved with another & at the end. java -jar /home/user/files/simulator.jar -nogui:/home/user/files/my-sims/sim1.csc &> /dev/null & Thanks a lot.
Well yes, that will run your program in background.
