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 and installed manually.

• Python v2.6+ is supported by release v19.
• Python v2.4+ is supported by release v12.

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.
