This script will allow you to effectively hard link a directory. It reproduces the directory structure of the source in the destination and then recursively hard links all the files from the source to the corresponding location in the destination. If you've ever wanted to hard link a folder, this produces the results you want.
#!/bin/bash
oldifs=$IFS
IFS='
'
[ $# -ne 2 ] && { echo "Usage: $0 sourceDirectory destinationDirectory" ; exit 1; }
[ ! -d "$1" ] && { echo "$1 is not a valid directory"; exit 1; }
[ ! -d "$2" ] && { mkdir -p "$2"; }
src=$(cd "$1" ; pwd)
dst=$(cd "$2" ; pwd)
find "$src" -type d |

a little bash toy to help find branches easier
#!/bin/bash
GIT=`which git`
FOUND=`$GIT branch | grep $1 | sed -e 's/^[ *] //' | sed -e 's/remotes\/origin\///g' |sort -u`
NUM_FOUND=`echo $FOUND|wc -l`
echo
if [ $NUM_FOUND -gt 1 ]; then
echo 'FOUND THESE MATCHING BRANCHES'
echo
echo "$FOUND"

this will try to detect your Jira ticket id from your branch name and insert it into your commit message
#!/bin/bash
BRANCH_NAME=$(git symbolic-ref --short HEAD)
if [ -z "$BRANCH_NAME" ]; then
exit 0
fi
if [ "master" = "$BRANCH_NAME" ]; then
exit 0
fi
