A simple utility that allows you to easily save your current working diretory by assigning it a named bookmark. You can then easily cd mybookmark, or use your bookmark as a Bash variable.

mtorok (Desktop)$ cd test_1/
mtorok (test_1)$ bookmark tests
Created bookmark tests to /Users/mtorok/Desktop/test_1
mtorok (Desktop)$ cd tests
/Users/mtorok/Desktop/test_1
mtorok (test_1)$ cd ..
mtorok (Desktop)$ showbookmarks 
tests=/Users/mtorok/Desktop/test_1
mtorok (Desktop)$ rm -rf $tests
mtorok (Desktop)$ rmbookmark tests
mtorok (Desktop)$ 

Save bash-bookmarks.sh somewhere on your system and add the following line to your ~/.bash_profile:

[[ -s ~/bash-bookmarks.sh ]] && . ~/bash-bookmarks.sh

Change the path to bash-bookmarks.sh to reflect its location on your system. Close and re-open Bash and the bookmark commands should be available.

• bookmark name: Create a new bookmark named name, pointing to the current directory.
• showbookmarks: List all bookmarks.
• rmbookmark name: Delete the bookmark named name.

By default, bookmarks are stored in ~/.bookmarks. You can change this by setting the $BOOKMARK_FILE shell variable before bash-bookmarks.sh is first sourced, e.g. by adding the line BOOKMARK_FILE=~/Documents/bash-bookmarks to ~/.bash_profile before the [[ -s ~/bash-bookmarks.sh ]] && . ~/bash-bookmarks.sh line.

Note that bookmarks aren't automatically transfered to any new file you specify, so if you want to keep existing bookmarks, you'll need to copy the old bookmark file to the new file.

Note also that if you change this value, is is highly reccomended to close and re-open your prompt. Otherwise, bookmarks from the old file will still be visible, yet all add/list/delete operations will happen over the new bookmark file.

All bookmark names must obey Bash variable naming rules: they must be one word, start with a letter or underscore, and contain only letters, numbers and underscores.

You can only bookmark your current working directory. If there is demand, support may be added for bookmarking arbitrary directories.

There are a number of similar utilities floating around the net. This one was inspired by a page I've since lost, and adapated heavily for my use. If you recognize the base script, drop me a line so that I may credit it properly.
