I am using ubuntu gnome 14.04 and I want to have tmux and zsh opened when I start a new terminal.

For now, in my preference of the terminal, I run tmux by default.

In the ~/.tmux.conf file I have this :

set-option -g default-shell /bin/zsh

It works but I have a problem with colors so I need to use TERM=xterm-256color tmux to run tmux. I tried to replace the command launched by default but it produce this error : no such file of this type.

I tried to run zsh by default and I added this in my ~/.zshrc :

if [ "$TMUX" = "" ]; then TERM=xterm-256color tmux; fi

It works but it launch zsh then it launch another process with zsh again. It's not very clean and when I try to close the terminal, it say than I have an active process running.

What can I do to make it work?

Usually tmux should get the TERM parameter from your terminal emulator. So you could just set it to xterm-256color in your its configuration.

If this does not work for some reason, you can start tmux like that

tmux -2

The parameter -2 forces tmux to assume 256-color support. Additionally you can set default-terminal in your `~/.tmux.conf

set -g default-terminal "screen-256color"

tmux -2 works. I already had set -g default-terminal "screen-256color" in my ~/.tmux.conf. –  Dougui Apr 28 '14 at 10:00
