A short shell script to make switching between folders in a directory easier.

nav.sh

# repository navigation shortcut
nav(){
	# list all directories in ~/Repositories
	DIRS=`ls -l ~/Repositories | egrep '^d' | awk '{print $9}'`

	# and now loop through the directories:
	for DIR in $DIRS
	do
		if [[ $DIR = $1* ]]
		then
			cd ~/Repositories/$DIR
			break
		fi
	done
}
