#autojump is a faster way to navigate your filesystem. It works by maintaining a database of the directories you use the most from the command line. The jumpstat command shows you the current contents of the database. You need to work a little bit before the database becomes usable. Once your database is reasonably complete, you can “jump” to a commonly "cd"ed directory by typing:
where dirspec is a few characters of the directory you want to jump to. It will jump to the most used directory whose name matches the pattern given in dirspec.
Autojump supports tab completion.
