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
Autojump is now officially a part of Debian Sid, thanks to Tanguy Ortolos work (for policy reasons, it requires manual activation after installing, see /usr/share/doc/autojump/README.Debian). To install, type::
apt-get install autojump
Autojump is also available on the OSX Homebrew package manager::
brew install autojump
Autojump is also packaged for a number of other distros. Check the wiki for an up-to-date list! I would be very interested by packages for other distros. If you think you can help 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.
