NAME
       z - jump around


SYNOPSIS
       z [-h] [-l] [-r] [-t] [regex1 regex2 ... regexn]


AVAILABILITY
       bash, zsh


DESCRIPTION
       Tracks your most used directories, based on 'frecency'.

       After a short learning phase, z will take you to the most 'frecent' direc‐
       tory that matches ALL of the regexes given on the command line.


OPTIONS
       -h show a brief help message
       -l list only
       -r match by rank only
       -t match by recent access only


EXAMPLES
       z foo	 cd to most frecent dir matching foo
       z foo bar cd to most frecent dir matching foo and bar
       z -r foo	 cd to highest ranked dir matching foo
       z -t foo	 cd to most recently accessed dir matching foo
       z -l foo	 list all dirs matching foo (by frecency)


NOTES
       Installation:

       optionally:
	set $_Z_CMD in .bashrc/.zshrc to change the command (default z).

       put something like this in your $HOME/.bashrc:

	. /path/to/z.sh

       put something like this in your $HOME/.zshrc:

	. /path/to/z.sh
	function precmd () {
	  _z --add "$(pwd -P)"
	}

       cd around for a while to build up the db.

       PROFIT!!

       Frecency:

       Frecency is a portmantaeu of 'recent' and 'frequency'. It  is  a	 weighted
       rank  that depends on how often and how recently something occured. As far
       as I know, Mozilla came up with the term.

       In z, a directory that has low ranking but has been accessed recently will
       quickly	have higher rank than a directory accessed frequently a long time
       ago.


ENVIRONMENT
       A function _z() is defined.

       An alias $_Z_CMD='_z 2>&1' is defined. If not set, $_Z_CMD defaults to z.


FILES
       data is stored in $HOME/.z
