\n Background Terminal Sessions\n <\/h1>\n \n \n <\/header>\n\n <\/div>\n\n <\/div>\n\n <\/div>\n<\/section>\n\n\n\n

It is possible to run Linux commands in the background.  You are able to disconnect from the Virtual Machine (VM) and connect later, and commands continue to run in the background.  This is useful if you need to run code that takes a long time.<\/p>\n\n\n\n

Thetmux<\/em> command on the Linux command-line\u00a0allows you to do exactly this. Using tmux<\/em>\u00a0you can run commands\u00a0on the VM, logout, and reconnect to your running programs later.<\/p>\n\n\n\n

You can tell that you are running tmux<\/em> by the green bar along the bottom of your Linux command-line window.<\/p>\n\n\n\n

Creating a new session<\/h3>\n\n\n\n

This command will start a new tmux<\/em> session.\u00a0 You will see a new Linux command line that is running inside tmux.\u00a0 Each tmux<\/em> session has a name, so you can have different sessions, and reference them by their unique names.<\/p>\n\n\n

\n
\n

tmux new -s example01<\/p>\n<\/blockquote>\n<\/div>\n\n\n

Leaving (detaching) a session<\/h3>\n\n\n\n

This leaves a session, but it will keep running so you can resume the session later. When you are in your tmux<\/em> session, type:<\/p>\n\n\n

\n
\n

Ctrl-b<\/em> followed by d<\/em><\/p>\n<\/blockquote>\n<\/div>\n\n\n

Listing sessions<\/h3>\n\n\n\n

You can have more than one tmux <\/em>session.\u00a0 To see the list of running sessions, use this command:<\/p>\n\n\n

\n
\n

tmux ls<\/p>\n<\/blockquote>\n<\/div>\n\n\n

Resuming (attaching) a session<\/h3>\n\n\n\n

When you want to reconnect to a session that you have already started, use this command:<\/p>\n\n\n

\n
\n

tmux attach -t example01<\/p>\n<\/blockquote>\n<\/div>\n\n\n

Stopping (killing) a session<\/h3>\n\n\n\n

Once you are finished with a tmux <\/em>session, you can get rid of it using this:<\/p>\n\n\n

\n
\n

tmux kill-session -t example01<\/p>\n<\/blockquote>\n<\/div>\n\n\n
