The autojump from revskill10

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:

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 v2.7, 3.0, or 2.6 with argparse
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.

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
```

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.
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

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.
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.
