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

tmux shortcuts & cheatsheet

start new:

tmux

start new with session name:

tmux new -s myname

Open all files with git merge conflicts in MacVim

git diff --name-only | uniq | xargs mvim

When git encounters a merge conflict, e.g. during a rebase, it drops you back into the shell with a dirty working directory. I like this one-liner for opening all files with a merge conflict in MacVim.

Once you're in Vim, you can then switch between the files with :n and :prev, or another favourite: :w | n (save current file and open the next command line-supplied file).

UPDATE: see below for a version that works with real terminal commands.

Remove rbenv and any rubies, gems etc.:

$ rm -rf ~/.rbenv

Uninstall rbenv if installed via Homebrew

$ brew uninstall rbenv

Remove references to rbenv in ~/.bash_profile etc.

	Steps to install and run PostgreSQL 9.2 using Homebrew (Mac OS X)
	(if you aren't using version 9.1.5, change line 6 with the correct version)

	1. pg_ctl -D /usr/local/var/postgres stop -s -m fast
	2. mv /usr/local/var/postgres /usr/local/var/postgres91
	3. curl https://raw.github.com/fragility/homebrew/737af01178590950749cf5e841f2d086c57c5a80/Library/Formula/postgresql.rb > /usr/local/Library/Formula/postgresql.rb
	4. brew upgrade postgresql
	5. initdb /usr/local/var/postgres -E utf8
	6. pg_upgrade -b /usr/local/Cellar/postgresql/9.1.5/bin -B /usr/local/Cellar/postgresql/9.2.0/bin -d /usr/local/var/postgres91 -D /usr/local/var/postgres
	7. pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start

	# Outputs this at warn log level:
	# 1.2.3.4 GET /path 200 OK BlahController#action HTML 938.2 (DB 11.8, View 719.7) {params} {optional params from flash[:log]}
	#
	# Save as config/initializers/oneline_detailed_logging.rb. Consider
	# decreasing the log level from "info" to "warn" (in production.rb) so
	# the one-line log message replaces the standard request logs.


	# override process_action to add 2 things to the payload:

	# Open the file you wish to encode
	data = File.open('/Users/bkenny/Desktop/d3cce16ee41411e296c022000a1f980f_101.mp4').read

	# Encode the puppy
	encoded = Base64.encode64(data)

	# Spit it out into one continous string
	puts encoded.gsub(/\n/,"")

	class Medium < ActiveRecord::Base
	serialize :payload, JSON
