How to Run a Process in the Background with TMUX

There are times when you need to log off your Linux Desktop, and you want a process to run in the background. TMUX manages this very well.

For this example, let's suppose you're running a long running task like running rspecs on your project and it is 5pm, and you need to go home.

Run Your Process

1. First launch TMUX

$ tmux

2. Run your long running process

$ bundle exec rspec spec

3. Detach from TMUX

Simply press [CTRL]+[b], then [d]. This will detach your session from TMUX

4. Log off

Now you can simply log off

Return to your session

$ tmux attach

OR

$ tmux a

  • Create a new tab: [CTRL]+[b], [c]
  • Switch to tab number: [CTRL]+[b], <number>
  • Enable Scrolling up / Page up: [CTRL]+[b], [
