Tmux configuration conditional to OS

tmux

There's some lines of my tmux.conf which I'd like executed only if my OS is Mac. However, I'd like to use my tmux.conf on multiple different operating systems. How can I make a command conditional to the OS on which tmux is currently running?

Best Answer

Use the if-shell command:

if-shell "uname | grep -q Darwin" "tmux-cmd1; tmux-cmd2;" "tmux-cmd3; tmux-cmd4"

You may want to put OS-specific commands in separate files, and execute them via the "source-file" command.

if-shell "uname | grep -q Darwin" "source-file .tmux-macosx" "source-file .tmux-linux"

Disallowing windows to rename themselves in tmux

I had similar problem but with byobu-screen and after some research, it turned out that it is oh-my-zsh feature.

This has been discussed on oh-my-zsh issues page

In short, I had to uncomment DISABLE_AUTO_TITLE="true" line in my ~/.zshrc file.

Based on the version of oh-my-zsh, you may have to add export DISABLE_AUTO_TITLE="true".

Tmux configuration stanzas based on Tmux version

Is there a method by which I can suppress this output?

Yes. The set-option and set-window-option commands take a -q ("quiet") flag, which suppresses errors about unknown options. This should cover you:

set-window-option -gq mouse off
set-window-option -gq mode-mouse off
set-option -gq status-utf8 on
set-window-option -gq utf8 on
