How to auto restart command/ process in Linux after specific run time or duration (quick-note)

Context

You want to auto-restart a command or process in Linux after specific run time, duration or time period.

For this you can use the timeout command in a while loop.

while true; do
    timeout 10 htop --tree
    true # you have to have true so that the while lop doesn't break. You might also do en echo.
done

where:

• timeout 10 means 10 seconds
• htop --tree is the command you want to run

You may also use echo instead of true after the command

while true; do
    timeout 10 htop --tree
    echo "restarting process..."
done
