Tmux has 3 interfaces for running commands and making configurations:
tmuxcommand available in your shell. All commands can be run directly against this, but note that any configurations set via the
tmuxcommand will be cleared when the server is shut down.
<prefix>:and will temporarily take over the tmux status bar. Note, there is no need to type
tmuxbefore a command when in the command prompt. Also, just like with the executable, any configurations made will be cleared when the server is shut down.
.tmux.conffile - The final (and primary) method for configuring tmux, this file lives in your home directory and is read by tmux when the server first starts up (when you start your first session). The configuration syntax is identical to what you run against the executable or in the command prompt, so both can be used to test out commands and configurations prior to adding them to your
.tmux.conf. This file will be read every time the server starts up but will not be read when opening new windows, panes, or sessions after the server starts. See below for how to reload the config file manually.
Add the following to your
.tmux.conf to allow for reloading your
.tmux.conf. This allows for rapid iteration on your configuration and
making sure any updates you make to your tmux configuration will persist for
bind-key r source-file ~/.tmux.conf \; display-message "~/.tmux.conf reloaded"
By default, all tmux key-bindings will require you to type the prefix key sequence first, then the desired key to activate the binding. There are two flags that can be used to circumvent the prefix key:
-n- This flag allows the key-binding to run without need for the prefix key. Note, since tmux wraps all terminal interaction, setting any key-binding with the
-nflag will essentially prevent you from sending that sequence through to underlying processes such as Vim since tmux will catch the key sequence and act on it.
-r- This flag allows key-bindings to be repeated without requiring the prefix key.
status-right option configures the text displayed on the right side of
the tmux status bar and configured with a combination of:
#Sfor the session name will be replaced with the corresponding value. See the
FORMATSsection of the tmux man page for more options.
#(...), and it will be replaced with its output.
