tmux

As configured in my dotfiles, here and here.

Command line

$ tmux                           -> start new
$ tmux new -s myname             -> start new w/session name
$ tmux a  #  (or at, or attach)  -> attach
$ tmux a -t myname               -> attach to named
$ tmux ls                        -> list sessions
$ tmux kill-session -t myname    -> kill session w/name

Shortcuts (via .oh-my-zsh/plugins/tmux/tmux.plugin.zsh)

ta = tmux attach -t
ts = tmux new-session -s
tl = tmux list-sessions
tksv = tmux kill-server
tkss = tmux kill-session -t

Quick, oft-used shortcuts (defined in ~/.tmux.conf)

alt-arrow    -> toggle pane in arrow direction

Tmux command mode - in tmux, type the prefix (default is `ctrl+b`, I use `ctrl+q`) and then:

1. Enter copy mode           $ <prefix> [
2. Enter selection mode      $ v
3. Move to end of selection  $ arrows or hjkl
4. Copy selected text        $ y or <Enter>

Notes:

You can cmd+click URLs to open in iTerm.
You can cmd+double-click strings to select w/iTerm (and the cmd+c to copy)
- HOWEVER: If you are copying text and multiple tmux panes are open, it will copy across panes! This is usually undesirable. It is recommended to use the above copy-paste instructions for copying to the system clipboard from within tmux.
