I jump around a lot in the terminal between different projects and activities. To avoid endless typing I have created aliases which allows me to quickly perform this task.

By adding the following entries to your `.bashrc` you will give access to the powerfull tools of `jcd` `scd` `lcd`. First and foremost goto a directory you would like to earmark. Type `scd <alias-of-choice>` and your entry will be stored. To go back to this directory type `jcd <stored-alias>` and you arrived at your destination. Tab completion also works to save typing some more.

```bash

function jcd {
	cd "$(grep "${1:-blank} /" ~/.jcd | cut -d' ' -f  2-)"
}

function scd {
	( grep -v "^${1:-blank} /" ~/.jcd; echo ${1:-blank} `pwd` ) > ~/.jcd.new
	mv ~/.jcd.new ~/.jcd
}

function lcd {
	cat ~/.jcd | sed 's/ /\t = /'
}

function _listcd {
	COMPREPLY=()
	cur="${COMP_WORDS[COMP_CWORD]}"
	opts=$(awk '{print $1}' ~/.jcd | grep "^$2")
	COMPREPLY=( $(compgen -W "${opts}" -- ${cur}) )
	return 0
}

complete -F _listcd jcd
complete -F _listcd scd
```
