So you have been working on your tmux workflow, you've dropped a too many window workflow for scoping work that belongs together into separate sessions, but you cannot remember what session your work is in. If your diligent you have named your window when you created it, but sometimes its intent has changed or your were just plain too lazy at the time for the extra characters needed to name it. Don't worry we can still give that session a descriptive name.
Let's rename some sessions in the terminal.
# rename the current session to me tmux rename-session me # rename the me session to scratch tmux rename-session -t me scratch
There is a default keybinding that you can use
<prefix>+$ to rename the current session in the tmux command line.
bind-key $ command-prompt -I #S "rename-session '%%'"
I've also had this keybinding kicking around for years, but I rarely use it anymore. You will see why in an upcoming video.
bind -n M-W command-prompt "rename-session '%%'"
