LinuxLoop

How to create a looped command in linux, that will run permanently in the background.
You must have a basic understanding of Linux to be able to follow this tutorial. I will not help with basic requests such as "how do I change directory".

Creating your loop file

1. touch loop.sh - Creates an empty file called loop.sh in the current directory.
2. nano loop.sh - Opens the file in the nano editor, feel free to use vim or your other favourite text editor.
3. Enter your contents:

#!/bin/bash
while true
do
    mycommandhere
    sleep 1
done

4. Replace mycommandhere with your command. It may be python run.py or something else, but make sure you take into account file paths when specifying where a file is.
5. Run it to ensure it works: bash loop.sh or /bin/bash loop.sh.
6. Send it off to the background however you like. You can simply use /bin/bash loop.sh &>/dev/null &. There are some caveats with this, so here's some links:

• Run in Background using Command
• Using Tmux
• Using Screen
• As a Service // Systemd
