1. count the occurence, just like uniq statment.

awk '{ tot[$0]++ } END { for (i in tot) printf("%s\t%s\n", i,tot[i]) }'

2. find multiple occurance of string in one lines

sed 's/\[http-/\n&/g; s/userid":/\n&/g;s/recmid":"/\n&/g;s/[^\n]*\nuserid":\([[:digit:]]*\)[^\n]*/\1 /g;s/.$//'

3. basic shell hashmap usage:

#!/bin/bash

function output_help {
        echo "usage: git-revert-single-file <sha1> <file>"
    }

sha1=$1
file=$2

if [[ $sha1 ]]; then

apt-get install git-core

Second, change to your home directory and create a new "bare repository" to deploy to.
cd ~/
mkdir repos && cd repos
mkdir awesomeblog.git && cd awesomeblog.git
git init --bare

Following that, we need to set up a post-receive hook. This is a shell script that Git runs when files are pushed to a repository. Create it like so:

lengerfulluse

#!/bin/bash

# where to store the sparse-image
WORKSPACE=~/UnixVolume.dmg.sparseimage

create() {
    hdiutil create -verbose -type SPARSE -fs 'Case-sensitive Journaled HFS+' -size 50g -volname UnixVolume ${WORKSPACE}
}

detach() {
