I just install tmux on Ubuntu 12.04 LTS and it throws me this error when I try to use tab completion for simple commands like 'cd' or 'mv' in the /etc/bash_completion file.

command substitution: line 74: syntax error near unexpected token `done'

However, I can use tab completion in my normal terminal or in byobu. Has anyone else encountered this issue or knows how to fix it? I do have the bash completion file included in my .bashrc.

I had the similar question, until I found this.

Pretty good, colorful, explanation.


  • /usr/share/byobu/keybindings/f-keys.tmux

  • /usr/share/byobu/keybindings/f-keys.tmux.disable

[recovered from cachd web page] Somewhere along the Ubuntu 12.04 LTS, tmux, bash development chain someone decided to add this little gem of a key binding: bind-key -n Tab clear-history They mapped that to clear the history, shutting down whatever else it may have done. This one is SO ODD, that I can only imagine there was some really good and crazy reason for it. To overcome this “feature” add the following to your .tmux.conf. unbind -n Tab – Alessandro Cuttin Feb 10 '15 at 14:45
