.SS NAME
.PP
autojump - a faster way to navigate your filesystem
.SS SYNOPSIS
.PP
Jump to a previously visited directory that contains \[aq]foo\[aq]:
.IP
.nf
\f[C]
j\ foo
\f[]
.fi
.PP
Jump to a previously visited subdirectory of the current directory:
.IP
.nf
\f[C]
jc\ bar
\f[]
.fi
.PP
Show database entries and their respective key weights:
.IP
.nf
\f[C]
j\ --stat
\f[]
.fi
.SS DESCRIPTION
.PP
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.
.SS OPTIONS
.PP
Options must be passed to \[aq]autojump\[aq] and not the \[aq]j\[aq]
wrapper function.
.IP
.nf
\f[C]
-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
\f[]
.fi
.SS ADVANCED USAGE
.IP \[bu] 2
Using Multiple Arguments
.RS 2
.PP
Let\[aq]s assume the following database:
.IP
.nf
\f[C]
30\ \ \ /home/user/mail/inbox
10\ \ \ /home/user/work/inbox
\f[]
.fi
.PP
\f[C]j\ in\f[] 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, \f[C]j\ w\ in\f[] would then jump you into
/home/user/work/inbox.
.RE
.IP \[bu] 2
Jump To A Child Directory.
.RS 2
.PP
Sometimes it\[aq]s convenient to jump to a child directory
(sub-directory of current directory) rather than typing out the full
name.
.IP
.nf
\f[C]
jc\ images
\f[]
.fi
.RE
.IP \[bu] 2
Open File Manager To Directories (instead of jumping)
.RS 2
.PP
Instead of jumping to a directory, you can open a file explorer window
(Mac Finder, Windows Explorer, GNOME Nautilus, etc) to the directory
instead.
.IP
.nf
\f[C]
jo\ music
\f[]
.fi
.PP
Opening a file manager to a child directory is also supported.
.IP
.nf
\f[C]
jco\ images
\f[]
.fi
.RE
.SS ADDITIONAL CONFIGURATION
.IP \[bu] 2
Enable ZSH Tab Completion
.RS 2
.PP
ZSH tab completion requires the \f[C]compinit\f[] module to be loaded.
Please add the following line to your ~/.zshrc \f[I]after\f[] loading
autojump:
.IP
.nf
\f[C]
autoload\ -U\ compinit\ &&\ compinit
\f[]
.fi
.PP
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:
.IP
.nf
\f[C]
autoload\ -U\ compinit\ &&\ compinit\ -u
\f[]
.fi
.PP
Tab completion requires two tabs before autojump will display the
completion menu.
However if \f[C]setopt\ nolistambiguous\f[] is enabled, then only one
tab is required.
.RE
.IP \[bu] 2
Always Ignore Case
.RS 2
.PP
Default behavior is to prioritize exact matches over all else.
For example, \f[C]j\ foo\f[] 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:
.IP
.nf
\f[C]
export\ AUTOJUMP_IGNORE_CASE=1
\f[]
.fi
.RE
.IP \[bu] 2
Prefer Symbolic Links
.RS 2
.PP
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:
.IP
.nf
\f[C]
export\ AUTOJUMP_KEEP_SYMLINKS=1
\f[]
.fi
.RE
.IP \[bu] 2
Autocomplete Additional Commands (Bash only)
.RS 2
.PP
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:
.IP
.nf
\f[C]
export\ AUTOJUMP_AUTOCOMPLETE_CMDS=\[aq]cp\ vim\[aq]
\f[]
.fi
.PP
Changes require reloading autojump to take into effect.
.RE
.SS KNOWN ISSUES
.IP \[bu] 2
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\[aq]t do this:
.RS 2
.IP
.nf
\f[C]
export\ PROMPT_COMMAND="history\ -a"
\f[]
.fi
.PP
Do this:
.IP
.nf
\f[C]
export\ PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND\ ;}\ history\ -a"
\f[]
.fi
.RE
.IP \[bu] 2
The jump function \f[C]j\f[] does not support directories that begin
with \f[C]-\f[].
If you want to jump a directory called \f[C]--music\f[], try using
\f[C]j\ music\f[] instead of \f[C]j\ \ \ --music\f[].
.SS FILES
.PP
If installed locally, autojump is self-contained in
\f[I]~/.autojump/\f[].
.PP
The database is stored in \f[I]$XDG_DATA_HOME/autojump/autojump.txt\f[].
