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.
Setting fish as default shell for tmux
Setting default shell is easy and can be done using the
default-shell command. It's better to set it in the global
set -g default-shell /bin/fish
You have to reload changes in tmux config
tmux.conf so that it reflects-
tmux source-file ~/.tmux.conf
You will have to kill your existing tmux sessions to make sure it reflects.
If the above doesn't help, use
htop to find all processes named
tmux and kill them all using the following command-
kill -9 <processid>
or if you need
sudo privileges to kill,
sudo kill -9 <processid>
