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 you 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 `autojump -s` 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:
<b>j</b> dirspec
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.

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*
## EXAMPLES
<b>j</b> mp3
j mp3
could jump to "/home/gwb/my mp3 collection", if that is the directory in which you keep your mp3s.
<b>j -s</b>
j --stat
will print out something in the lines of:

The "key weight" reflects the amount of time you spend in a directory.
*DOWNLOAD*
## DOWNLOAD
Use the [[github dowloads|http://github.com/joelthelion/autojump/downloads]] to get the latest release, or use git to get the bleeding edge version (should usually work)
*INSTALLATION*
## INSTALLATION
For automatic installation, make sure that install.sh is executable. If not (or if not sure), run <pre>chmod +x install.sh</pre>
Once it is executable, run <pre>./install.sh</pre> It will tell you any necessary steps from there.
Manual installation of autojump is very simple: copy autojump to /usr/bin, autojump.sh to /etc/profile.d, and autojump.1 to /usr/share/man/man1. Make sure you source /etc/profile in your .bashrc:

```source /etc/profile```
source /etc/profile.d/autojump.sh
If you do not have root access to your machine, copy @autojump@ to a directory that is in the @PATH@ (for example, @$HOME/local/bin@), copy @autojump.bash@ somewhere convenient, and add @source /path/to/autojump.bash@ in your @.bashrc@.
