When switching between tmux sessions with the interactive session menu (<prefix>-s), you can jump to a specific session by typing the session's numeric or alphabetical index, e.g.

(0) + first_session: 1 windows (1) + second_session: 2 windows (2) + third_session: 1 windows (3) + secret_session: 1 windows

Pressing 1 will open up the second_session session.

I often have >20 tmux sessions open and I'd like to have a way to search without looking at the whole list. Is there a way to change the behaviour to have an interactive search? That is, I would like to type sec and have the list narrow to

(1) + second_session: 2 windows (3) + secret_session: 1 windows

I've googled quite a bit and found nothing; is this behaviour possible?

Yes it is, but as far as i know you'll need an extra tool for the searching itself. I'm using fzf for the (fuzzy) searching. Once fzf is installed you can use the following config to set up the session switching with search:

bind C-j split-window -v "tmux list-sessions | sed -E 's/:.*$//' | grep -v \"^$(tmux display-message -p '#S')\$\" | fzf --reverse | xargs tmux switch-client -t"

I didn't figure this out myself but took this from Chris Toomey's public tmux conf.

@bartj3: Thanks. This is super cool!

Here is a slightly enhanced version (w/o sed and grep) for both switching sessions and windows:

bind j split-window -v "tmux list-sessions -F '#S' | fzf --reverse | xargs tmux switch-client -t"
bind k split-window -v "tmux list-window -F '#W' | fzf --reverse | xargs tmux select-window -t"

PROBLEM:

If you use the above while synchronize-panes is on, your search key-strokes will also type in the other panes.

QUESTION:

Does anyone have an idea on how to limit the key-strokes to the search-pane?
