tmux exits abruptly right after loading

zsh tmux

5,744

Solution 1

The input_parse lines from the verbose logging show you the output from the initial command that tmux is running. It can be hard to read them when they are presented one character at a time like that, though. Here is the reassembled output:

/home/john/.zprofile:2: no such file or directory: /n/sw/zsh-4.3.14/bin/zsh

tmux starts login shells for its default commands. when zsh is started as a login shell, it processes ~/.zprofile (if it exists). Your version of this file is trying to run a file that does not exist: /n/sw/zsh-4.3.14/bin/zsh.

You might need to comment out or adjust something in your ~/.zprofile file. Or maybe you need to mount the expected filesystem on /n/sw?

Solution 2

This seems to be caused by a syntax error somewhere in your dotfiles. Common places to look: .zshrc (or .bashrc, .bash_profile, etc.), and of course .tmux.conf.

In my case I forgot to put quotes like so: DISABLE_UPDATE_PROMPT=true should have been DISABLE_UPDATE_PROMPT='true'

I just compiled my own version of tmux with libevent. Whenever I run tmux from zsh, tmux starts, but exits quickly returning [exited]. I read here that the problem could be my configuration for default-command, default-shell, but I don't have a .tmux.conf file on my home directory, and as far as I know there is no version of tmux installed on the system.

Interestingly though, tmux runs correctly with:

tmux new $SHELL

I have also tried creating an empty .tmux.conf with no luck, and tmux -v does not output anything else.

any thoughts?
