Yesterday I discovered tmux - what an awesome command line tool!
So powerful, yet so easy to use (and configure!).
If you haven't heard of tmux before, but have used GNU screen then tmux is basically an enhanced screen replacement.
It allows you to set up a set of windows (with panes and tabs), detach from the session, and later reattach. You can also attach multiple users to a tmux session (which is great for pair programming - or if you are giving someone a tour of a server).
Interested You should buy this book - it's short and great:
https://pragprog.com/book/bhtmux/tmux
Basic commands:
New Session
tmux new -s [-d]
Attach to Session
tmux attach -t
Kill Session
tmux kill-session -t
List Sessions
tmux ls
All key commands start with a prefix (by default it is configured to be ctrl+b), most people change this to ctrl+a by the looks of things.
Windows
New Window (c)
Select Window (0-9)
Rename Window (,)
Detach (d)
Panes
Vertical Split (") - a good replacement for this is (|)
Horizontal Split (%) - a good replacement for this is (-)
Swap Panes ({})
Select Pane UDLR
Close Pane (x)
Cycle Pane (o)
Turn Page Into a New Window (!)
- Here is my current tmux config (place in ~/.tmux.conf):
# Setting the prefix from C-b to C-a
set -g prefix C-a
# Free the original Ctrl-b prefix keybinding
unbind C-b
#setting the delay between prefix and command
set -s escape-time 1
# Ensure that we can send Ctrl-A to other apps
bind C-a send-prefix
# Set the base index for windows to 1 instead of 0
