An incomplete cheatsheet for rails 3. Things are added as they are required.

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

Copy, with line wrapping!

If you've been trying to copy/paste text from a multi-pane tmux session with the mouse, you've probably been pretty pissed at the blissful ignorance a terminal application has of the rodent in your hand.

The alternative, which is quote-unqoute native copy/pasting using copy-mode takes a bit to get used to. So this is one solution for copying and pasting lines from a session with correct line wrapping behaviour, albeit keyboard only.

Disclaimer

Since copy-mode has similar concepts of marks, regions, and temp buffers to Emacs .. you'll probably find it straight forward if you're familar with Emacsen. For people using vi-mode in tmux, the same still applies but obviously the default key bindings will differ alot from what I show below.

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a
