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](https://github.com/joelthelion/autojump/downloads) and
installed manually.
- Python v2.4 is supported by [release
v12](https://github.com/downloads/joelthelion/autojump/autojump_v12.tar.gz).
### 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](https://github.com/joelthelion/autojump/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
Unit tests are available in `./tests/`. Run unit tests with the command:
make test
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 *\$XDG*DATA\_HOME/autojump/autojump.txt\_.
