How can I start tmux without allowing it to read any configuration files?

(I have a server with only one account, so I have to share many configuration files of many programs. This means, I cannot delete .tmux.conf etc.)

  • I assume that one shared account is the root account. If so, why don't you set up a new administrative account just for yourself?

Reset to default

The -f option tells tmux to use the specified configuration file instead of the default (/etc/tmux.conf and ~/.tmux.conf). You can point it at /dev/null to skip configuration entirely:

tmux -f /dev/null

or use your own configuration:

tmux -f ~/.tmux.plhn.conf

This will only work when starting tmux; if a tmux server is already running, its configuration can’t be changed in this way.

    Note: You can use a different tmux socket to avoid having to kill tmux in order to test with an empty config. tmux -L test -f /dev/null
