Jump to running tmux sessions with fzf

#cli #linux #tmux

Quickly getting between tmux splits is critical skill for productivity. You
can get by with next or prev session for awhile, but if you have more than
about three session you need something a bit more targeted.

Full Screen selector

I have used this fzf one keybinding for quite awhile, honestly I did not make
it up, and cannot remember where it came from. It will open up a session picker
in a new full screen window.


 bash
bind C-j new-window -n "session-switcher" "tmux list-sessions | sed -E 's/:.*$//' | grep -v \"^$(tmux display-message -p '#S')\$\" | fzf --reverse | xargs tmux switch-client -t"
Enter fullscreen mode Exit fullscreen mode

Popup selector

Like with many of my keybindings I have swapped this one out for a popup
version. It just feels so smooth.


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

Hiya! I noticed that trying to escape from the popup still ends up selecting the session that was highlighted. How can you set it up such that esc or C-c just dismisses the popup and doesn't do anything?

One thing to note: the display-popup command was only introduced in the latest release of tmux, version 3.2. At this time, some distros still have 3.1c in the package repos (for example, Ubuntu 21.04), so tmux needs to be built from source. Worth it though.

Then session listed in fzf preview are sorted by name, there is snippet that show them by last visited order.

bind -n M-j display-popup -E "\
    tmux list-sessions -F '#{?session_attached,,#{session_activity},#{session_name}}' |\
    sort -r |\
    sed '/^$/d' |\
    cut -d',' -f2- \|
    fzf --reverse --header jump-to-session --preview 'tmux capture-pane -pt {}'  |\
    xargs tmux switch-client -t"
Enter fullscreen mode Exit fullscreen mode
