Execute a command via SSH and terminate the connection without waiting for the command to finish

A few days ago I was trying to update the script used to build the application on which I’m working. Together with the build I also wanted to integrate the script so to release the app on test boxes and restart the JBoss instance.

While the stop was working as a piece of cake, the restart of the server was keeping my ssh connection alive, and causing the release script to not finish.

After a bit of googling that the ssh syntax you’ll have to use if you want to send a command via ssh, redirect std out/err, and close the ssh connection:

ssh username@host “nohup command_to_execute > /dev/null 2>&1 > /../log_folder/log_file &”

Hope this will help someone of you out there 🙂
