Introduction
This is almost too simple for a whole wiki page, but snippets that maybe useful in emergency situations deserve a clazzes.org page by definition ...
Some tasks run too long for one "office chair session". Some other tasks require a lot of shell environment preparation.
In both situations a long-lived shell that can be accessed from different client machines can be very useful.
tmux provides such a shell.
tmux snippets
The following examples assume that the detachable shell shall run on a remote machine.
Obviously, tmux has to be installed:
sudo apt-get install tmux
Creating a detachable shell
ssh user@host tmux # start whatever task shall run
Detaching
Press Ctrl-b d, i.e. press and hold Control, press B, unhold Control, press D.
Re-Attaching
ssh user@host tmux attach
Frequently used options
| Option | Purpuse |
|---|---|
| -L socket-name | Uses specified socket-name instead of 'default'. Useful to run and distinct multiple tmux daemons. |
| -S socket-path | Uses specified socket-path instead of default path and name. Useful to run and distinct multiple tmux daemons. |
Further features and reading
tmux can do much more, i.e. run multiple commands (i.e. shells) and so on.
Just read the tmux(1) manpage, especially chapters KEY BINDINGS, COMMANDS, and below.
