AUTOJUMP
A cd command that learns
One of the most used shell commands is cd. A quick survey among my friends revealed that between 10 and 20% of all commands they type are actually cd commands! Unfortunately, jumping from one part of your system to another with cd requires to enter almost the full path, which isn't very practical and requires a lot of keystrokes.
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:
j dirspec
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. Note that autojump isn't meant to be a drop-in replacement for cd, but rather a complement. Cd is fine when staying in the same area of the filesystem; autojump is there to help when you need to jump far away from your current location.
Autojump supports tab completion. Try it! Autojump should be compatible with bash 4. Please report any problems!
Pierre Gueth contributed a very nice applet for freedesktop desktops (Gnome/KDE/...). It is called "jumpapplet", try it!
Thanks to Simon Marache-Francisco's outstanding work, autojump now works perfectly with zsh.
Examples
j mp3
could jump to /home/gwb/my mp3 collection, if that is the directory in which you keep your mp3s.
jumpstat
will print out something in the lines of:
... 54.5: /home/shared/musique 60.0: /home/joel/workspace/coolstuff/glandu 83.0: /home/joel/workspace/abs_user/autojump 96.9: /home/joel/workspace/autojump 141.8: /home/joel/workspace/vv 161.7: /home/joel Total key weight: 1077
The "key weight" reflects the amount of time you spend in a directory.

Installation
Auto Installation
run:
./install.sh
or:
./install.zsh
depending on your shell. Enter your root password if it asks.
Add the line:
source /etc/profile
to ~/.bashrc or ~/.zshrc if it isn't already there.
Troubleshoot
If the script fails, you may need to do:
chmod +x install.(z)sh
before the first step.
Manual installation of autojump is very simple: copy
- autojump to /usr/bin,
- autojump.sh to /etc/profile.d,
- autojump.1 to /usr/share/man/man1.
Make sure to source /etc/profile in your .bashrc or .zshrc
source /etc/profile
Packaging
For now gcarrier and I have packaged autojump for Arch Linux. It is available in [community]. To install, type:
pacman -S autojump
I would be very interested by packages for other distros. If you think you can help me with the packaging, please contact me!
Uninstallation
To completely remove autojump you should remove these files:
/etc/profile.d/autojump.bash
/etc/profile.d/autojump.sh
/etc/profile.d/autojump.zsh
/usr/bin/autojump
/usr/bin/jumpapplet
/usr/share/autojump/icon.png
/usr/share/autojump/
/usr/share/man/man1/autojump.1
Remove any mention of autojump in your .bashrc or .zshrc, then in currently running shells do:source /etc/profile.
If you keep getting autojump: command not found at the Bash prompt, do:unset PROMPT_COMMAND. You can also restart your shell.
