Enable git-style colour output in regular diff

Mac OS X

1. Install colordiff using Homebrew:

    brew install colordiff
   

2. Add function to your ~/.bash_profile:

jaygooby

#!/bin/bash
#
# Carries out a full mysqldump, calls percona-xtrabackup and then
# copies the sql dump, the percona backup and your mysql bin logs
# to S3 using s3cmd http://s3tools.org/s3cmd
# 
# TODO: extract out the S3 backup stuff to make it optional, and so
# other s3 programs can replace the s3cmd call.
# TODO: the if [ $? == 0 ] alert blocks should be a function
# TODO: make the if [ $? == 0 ] if [ $? != 0 ] more consistent - test

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"
