Tmux is one of the most useful tool when it comes to using using a linux terminal.
Tmux is a terminal multiplexer, it allows a user to access multiple terminals (or windows), each running a separate program, while providing a single screen to work on. Tmux is useful for running more than one command-line program at the same time, increasing productivity and the way you work.
Let's say you have made changes to
tmux.conf file by adding or changing default config, you have to reload the config so that the changes reflects in your terminal. The command to reload config is called
Reload Tmux - Tmux Source Config
You have to reload
tmux.conf so that it reflects-
tmux source-file ~/.tmux.conf
If you are inside a tmux session, you can run the command inside the tmux session to source the config file-
prefix : source-file ~/.tmux.conf
By default the prefix is
Ctrl-B, so to reload the tmux conf you can run the following command-
Ctrl-B : source-file ~/.tmux.conf
Edit Tmux Config to create a shortcut - Ctrl-R
You can edit the
tmux.conf file to create a keyboard shortcut
bind r source ~/.tmux.conf\\; display "~/.tmux.conf sourced!"
Going forward you can just do
Ctrl-R in your tmux, and enjoy instant tmux reload.
