After updating my /etc/shell file and typing a csh -s /usr/local/bin/zsh afterwards, I decided to quit and relaunch tmux with hope it will take account of my new $SHELL environment variable. Unfortunately, tmux still shows the old /bin/zsh after typing echo $SHELL.

How to tell tmux to inherit the $SHELL variable of the shell that launched it?

CodePudding user response：

set-option -g default-shell "$SHELL_PATH"

in ~/.tmux.conf or /etc/tmux.conf. Works on arch.

You can reload the config file with : source-file e.g.

<C-b>: source-file ~/.tmux.conf

You would need to do it for every tmux instance. Otherwise you may restart

tmux with killall tmux; tmux

these commands will change the path of shell in tmux
