You've stumbled upon Matt Scilipoti's "personal" cheat sheet.
Bash
============
== Reset terminal when text is borked
$ reset
== To list all environment variables
$ printenv
Debug
=============
arspy
git
=================
== config recommendations
[push] default=tracking
== tracking
# creates a local branch, tracking the remote, witht the same name as the remote
gco --track origin/name_of_remote_branch
== remove need for `origin master`
[branch "master"]
remote = origin
merge = refs/heads/master
== remote branches
#remove remote
git push origin :<remote_branch_name>
#refresh list
git remote prune origin
== only push the current branch
git config --global push.default current
== compare
git log --left-right --graph --cherry-pick --oneline master...stage_master
guard
========
## Show rspec results in growl AND in terminal
see: https://github.com/vizjerai/guard-spin/issues/6#issuecomment-6628816
# Gemfile
group :test, :development do
gem 'growl-rspec'
end
# .rspec
--require growl-rspec --format "Growl::RSpec::Formatter" --colour --format documentation
haml
=========
Surround tag with parens:
= "(%s)" % link_to("Edit", ...)
:ruby for ruby
*nix
=========
ncdu: disk usage
lsof: who is using file
== file count (-f: don't sort)
$ ls -f | wc -l
== clear a file
$ echo -n > file
== fix 'no init':
$ sudo fdisk -l
$ sudo fsck /dev/sda1
== boot record
$ update-initramfs -u
$ update-grub
== Who is serving on port 3000?
$ lsof -w -n -i tcp:3000
== redirect stderr to null
$ find /Volumes/Space -name 'cx_production*' 2> /dev/null
== fix prompt when not echoing key presses
$ stty sane
== ascii art
figlet: http://www.go2linux.org/figlet-create-nice-signatures-emails-forums-usenet-708.html
== cd in bash? source it
$ . cdd karma
~/bin/cdd
sub_directory=$1
working_dir=`find ~/develop/ -name $sub_directory -type d`
if test -d $working_dir; then
echo "cd to $working_dir"
cd $working_dir
...
osx
=============
Character Palette: Command-Option-T.
