NAME
----

autojump - a faster way to navigate your filesystem

SYNOPSIS
--------

Jump to a previously visited directory 'foobar':

    j foo

Show all database entries and their respective key weights:

    jumpstat

DESCRIPTION
-----------

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. Directories must be visited first before they can be jumped
to.

INSTALLATION
------------

### REQUIREMENTS

-   Python v2.7+ or 3.2+
-   Bash v4.0+ for tab completion

If you are unable to update Python to a supported version, older
versions of autojump can be
[downloaded](https://github.com/joelthelion/autojump/downloads) and
installed manually.

-   Python v2.6+ is supported by [release
    v19](https://github.com/downloads/joelthelion/autojump/autojump_v19.tar.gz).
-   Python v2.4+ is supported by [release
    v12](https://github.com/downloads/joelthelion/autojump/autojump_v12.tar.gz).

### MANUAL INSTALLATION

Grab a copy of autojump:

    git clone git://github.com/joelthelion/autojump.git

Run the installation script:

    cd autojump
    ./install.sh [ --local ] [ --zsh ]

and follow on screen instructions.

### MANUAL UNINSTALLATION

It is recommended to use your distribution's relevant package management
utilities, unless you installed manually or ran into uninstallation
issues.

Grab a copy of autojump:

    git clone git://github.com/joelthelion/autojump.git

Run the uninstallation script:

    cd autojump
    ./uninstall.sh

and follow on screen instructions.

If you keep getting `autojump: command not found` at the prompt,
do:`unset PROMPT_COMMAND`. You can also restart your shell.

OPTIONS
-------

Options must be passed to 'autojump' and not the 'j' wrapper function.

    -a, --add DIR       manually add path to database

    --stat              show database entries and their key weights

    --version           show version information and exit

INTERNAL OPTIONS
----------------

    -b, --bash          enclose directory with quotes to prevent errors

    --complete          used for tab completion

ADDITIONAL CONFIGURATION
------------------------

-   Always Ignore Case

    Default behavior is to prioritize exact matches over all else. For
    example, `j foo` will prefer /foobar over /FooBar even if the latter
    has a higher weight. To change this behavior and ignore case, add
    the following environmental variable in your \~/.bashrc:

        export AUTOJUMP_IGNORE_CASE=1

-   Prevent Database Entries' Decay

    Default behavior is to decay unused database entries slowly over
    time. Eventually when database limits are hit and maintenance is
    run, autojump will purge older less used entries. To prevent decay,
    add the following variable in your \~/.bashrc:

        export AUTOJUMP_KEEP_ALL_ENTRIES=1

-   Prefer Symbolic Links

    Default behavior is to evaluate symbolic links into full paths as to
    reduce duplicate entries in the database. However, some users prefer
    a shorter working directory path in their shell prompt. To switch
    behavior to prefer symbolic links, add the following environmental
    variable in your \~/.bashrc:

        export AUTOJUMP_KEEP_SYMLINKS=1

ADVANCED USAGE
--------------

-   Change Directory Weight

    To manually change a directory's key weight, you can edit the file
    *$XDG\_DATA\_HOME/autojump/autojump.txt*. Each entry has two
    columns. The first is the key weight and the second is the path:

        29.3383211216   /home/user/downloads

    All negative key weights are purged automatically.

KNOWN ISSUES
------------

-   zsh (bug \#86)

    Tab completion does not work.

-   jumpapplet (bug \#59)

    Does not work in Gnome 3 shell or LDXE.

FILES
-----

If installed locally, autojump is self-contained in *\~/.autojump/*.

The database is stored in *$XDG\_DATA\_HOME/autojump/autojump.txt*.
