Is there any way to re-number or swap tmux sessions, just as you can renumber or swap tmux windows? I can't see any command for it and want to easily switch between certain sessions.

The default ordering seems to have changed recently from name to index. If you want to put it back to name, try this in your .tmux.conf

bind s choose-tree -sZ -O name

They're sorted by name (which defaults to a number) You can change the names so that they appear in the order that you prefer.

Outside of tmux:

tmux rename-session -t 0 zzz

inside tmux: C-b $

Or:

c-b : rename session -t current_name new_name

    They're not anymore. I named all of my sessions, and they're definitely not alphabetically sorted. – Iulian Onofrei Aug 04 '20 at 09:56

    It seems sessions are being ordered by index now (i.e. the order they're created). You can type `O` while in session list mode to cycle through the different sort orderings (including `sort: name`), however I haven't figured out how to persist this setting. – Cody Aug 24 '20 at 17:03

If you'd like to "manually" order your sessions, you can prefix the session name with a zero-width or invisible unicode character. For example: 

$ tmux rename-session -t charlie $(echo -e "\u200B")charlie
$ tmux rename-session -t beta $(echo -e "\u200C")beta
$ tmux rename-session -t alpha $(echo -e "\u200D")alpha
$ tmux list-sessions
charlie: 1 windows (created Sun Nov  2 12:39:30 2014) [284x87] (attached)
beta: 1 windows (created Sun Nov  2 12:39:27 2014) [284x87]
alpha: 1 windows (created Sun Nov  2 12:39:23 2014) [284x87]

The drawback is that you still have to refer to the session using those characters.
