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 working directory: jc bar Show all 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. The `j --stat` command shows you the current contents of the database. 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. -a, --add DIR manually add path to database --purge deletes database entries that no longer exist on system -s, --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 ------------------------ - Enable ZSH Tab Completion ZSH tab completion requires the `compinit` module to be loaded. Please add the following line to your \~/.zshrc: autoload -U compinit; compinit - 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 - 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. ADVANCED USAGE -------------- - 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. jo music - 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. jc images Opening a file manager to a child directory is also supported. jco images - 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. - ZSH Tab Completion Tab completion requires two tabs before autojump will display the completion menu. However if `setopt nolistambiguous` is enabled, then only one tab is required. - 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 ------------ - 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*.
