Configure tmux and zsh to play nicely

written by Eric J. Ma on 2021-02-28 | tags: shell programming


I have been encountering this problem where tmux reloads my PATH environment variable incorrectly. As it turns out, the fix is documented in a StackOverflow post.

The crux of the problem is as follows: When tmux loads, my .zshrc is re-evaluated. By setting the following line in my .tmux.conf configuration file:

set -g default-command /bin/zsh

I can now prevent zsh from being instantiated as a login shell.

(If you're now wondering what in the world is a "login shell", fret not, I had to search online too. Here's the best answer I found, this time on StackExchange.)
