Diff is a very useful tool. But it is not so easy to read for us, simple mortal.

This is why, when you use git it will use a better formatting and colorize it.

Here is the script I use when I want to use human readable diff à la git.

#!/usr/bin/env zsh

Load colors helpers

autoload -U colors && colors

function colorize_diff { while read line; do case ${line[0]} in +) print -n $fg[green];; -) print -n $fg[red];; @) # Display in cyan the @@ positions @@ if [[ ${line[1]} = '@' ]]; then line=$(print $line | perl -pe 's#(@@[^@]@@)(.)$#'$fg[cyan]'$1'$reset_color'$2#') fi;;

esac
    print -- $line
    print -n $reset_color
    done

}

diff -u $* | colorize_diff
