bash_completion_tmux.sh but this does not complete command options or command aliases. So I wrote a better version which completes tmux commands, aliases and their options. However, there is still room for improvement. It would be nice if it could complete session and window names too, but I haven't found the time to implement this yet.
Here is a demo:
$ tmux lis[TAB] list-buffers list-clients list-commands list-keys list-panes list-sessions list-windows $ tmux list-windows -[TAB] -a -t $ tmux list-windows -a sharfah:0: less [180x82] [layout f0de,180x82,0,0] sharfah:1: tmp [180x82] [layout f0de,180x82,0,0] (active) sharfah:2: isengard [180x82] [layout f0de,180x82,0,0] sharfah:3: java [180x82] [layout f0de,180x82,0,0]My completion script is shown below. You need to source it in your Bash profile. Alternatively, save it to your Bash completion directory e.g.
~/.bash/.bash/.bash_completion.d and it should automatically get picked up.
The script is also available in my GitHub dotfiles repository. If you can improve it, fork it and send me a pull request!

Thanks a lot Fahd, this saved me a lot of time!
ReplyDeleteOne culprit though: associative arrays work only in bash >= 4, so it's a no go on most productive servers nowadays
