TMUX CHEAT SHEET

It is an application that allows you to split a terminal window into multiple others. So, in a single window, we can have several instances of the terminal open, similar to GNU screen or Byobu. Tmux is ideal for speeding up terminal tasks, especially if you are a sysadmin, who needs to handle several terminals in one.

Install

sudo apt-get install tmux

Sessions

  • Create a tmux session:

     tmux new -t ses_name

  • Detact from session: Ctrl + b   d

    Running commands in a session is still run after you detach from session. This is one of the best features of tmux.

  • Attach to an detached session:

     tmux a -t ses_name

  • Terminate tmux session:

     tmux kill-ses -t ses_name
