NAME

autojump - a faster way to navigate your filesystem

SYNOPSIS

Jump to a previously visited directory that contains 'foo':

j foo

Jump to a previously visited subdirectory of the current directory:

jc bar

Show database entries and their respective key weights:

j --stat

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

INSTALLATION

REQUIREMENTS

• Python v2.6+
• Bash v4.0 for tab completion (or zsh)

If you are unable to update Python to a supported version, older versions of autojump can be downloaded and installed manually.

• Python v2.4 is supported by release v12.

AUTOMATIC INSTALLATION

Linux

autojump is included in the following distro repositories, please use relevant package management utilities to install (e.g. yum, apt-get, etc):

• Debian* testing/unstable, Ubuntu, Linux Mint
• RedHat, Fedora, CentOS
• ArchLinux
• Gentoo
• Frugalware
• Slackware

* Requires manual activation for policy reasons, please see /usr/share/doc/autojump/README.Debian.

Mac

Homebrew is the recommended installation method for Mac OS X:

brew install autojump

MacPorts also available:

port install autojump

Other

Please check the Wiki for an up to date listing of installation methods.

MANUAL INSTALLATION

Grab a copy of autojump:

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

Run the installation script:

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

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.

DEVELOPMENT

The source code is primarily in ./bin/autojump. Various shell wrapper scripts are also available in ./bin/.

Documentation is in various files under ./docs/. Build documentation with the command:

make docs

OPTIONS

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

-i, --increase      manually increase current directory weight

-d, --decrease      manually decrease current directory weight

--purge             deletes database entries that no longer exist on system

-s, --stat          show general stats and top 100 database entries

--version           show version information and exit

ADVANCED USAGE

• Using Multiple Arguments

  Let's assume the following database:

  30   /home/user/mail/inbox
  10   /home/user/work/inbox
  

  j in would jump into /home/user/mail/inbox as the higher weighted entry. However you can pass multiple arguments to autojump to prefer a different entry. In the above example, j w in would then jump you into /home/user/work/inbox.

• Jump To A Child Directory.

  Sometimes it's convenient to jump to a child directory (sub-directory of current directory) rather than typing out the full name.

• Open File Manager To Directories (instead of jumping)

  Instead of jumping to a directory, you can open a file explorer window (Mac Finder, Windows Explorer, GNOME Nautilus, etc) to the directory instead.

  Opening a file manager to a child directory is also supported.

ADDITIONAL CONFIGURATION

• Enable ZSH Tab Completion

  ZSH tab completion requires the compinit module to be loaded. Please add the following line to your ~/.zshrc after loading autojump:

  autoload -U compinit && compinit
  

  For security compinit checks completion system if files will be owned by root or the current user. This check can be ignored by using the -u flag:

  autoload -U compinit && compinit -u
  

  Tab completion requires two tabs before autojump will display the completion menu. However if setopt nolistambiguous is enabled, then only one tab is required.

• 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
  

• 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
  

• Autocomplete Additional Commands (Bash only)

  Autojump can be used to autocomplete other commands (e.g. cp or vim). To use this feature, add the following environmental variable in your ~/.bashrc:

  export AUTOJUMP_AUTOCOMPLETE_CMDS='cp vim'
  

  Changes require reloading autojump to take into effect.

KNOWN ISSUES

• For bash users, autojump keeps track of directories as a pre-command hook by modifying $PROMPT_COMMAND. If you overwrite $PROMPT_COMMAND in ~/.bashrc you can cause problems. Don't do this:

  export PROMPT_COMMAND="history -a"
  

  Do this:

  export PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND ;} history -a"
  

• The jump function j does not support directories that begin with -. If you want to jump a directory called --music, try using j music instead of j --music.

FILES

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

The database is stored in $XDGDATA_HOME/autojump/autojump.txt_.
