20+
21+NAME
22+ z - jump around
23+
24+SYNOPSIS
25+ z [-chlrt] [regex1 regex2 ... regexn]
26+
27+AVAILABILITY
28+ bash, zsh
29+
30+DESCRIPTION
31+ Tracks your most used directories, based on 'frecency'.
32+
33+ After a short learning phase, z will take you to the most 'frecent'
34+ directory that matches ALL of the regexes given on the command line.
35+
36+OPTIONS
37+ -c restrict matches to subdirectories of the current directory.
38+
39+ -h show a brief help message
40+
41+ -l list only
42+
43+ -r match by rank only
44+
45+ -t match by recent access only
46+
47+EXAMPLES
48+ z foo cd to most frecent dir matching foo
49+
50+ z foo bar cd to most frecent dir matching foo and bar
51+
52+ z -r foo cd to highest ranked dir matching foo
53+
54+ z -t foo cd to most recently accessed dir matching foo
55+
56+ z -l foo list all dirs matching foo (by frecency)
57+
58+NOTES
59+ Installation:
60+ Put something like this in your $HOME/.bashrc or $HOME/.zshrc:
61+
62+ . /path/to/z.sh
63+
64+ cd around for a while to build up the db.
65+
66+ PROFIT!!
67+
68+ Optionally:
69+ Set $_Z_CMD to change the command name (default z).
70+ Set $_Z_DATA to change the datafile (default $HOME/.z).
71+ Set $_Z_NO_RESOLVE_SYMLINKS to prevent symlink resolution.
72+ Set $_Z_NO_PROMPT_COMMAND to handle PROMPT_COMMAND/precmd your-
73+ self.
74+ Set $_Z_EXCLUDE_DIRS to an array of directories to exclude.
75+ (These settings should go in .bashrc/.zshrc before the lines
76+ added above.)
77+ Install the provided man page z.1 somewhere like
78+ /usr/local/man/man1.
79+
80+ Aging:
81+ The rank of directories maintained by z undergoes aging based on a sim-
82+ ple formula. The rank of each entry is incremented every time it is
83+ accessed. When the sum of ranks is greater than 6000, all ranks are
84+ multiplied by 0.99. Entries with a rank lower than 1 are forgotten.
85+
86+ Frecency:
87+ Frecency is a portmantaeu of 'recent' and 'frequency'. It is a weighted
88+ rank that depends on how often and how recently something occured. As
89+ far as I know, Mozilla came up with the term.
90+
91+ To z, a directory that has low ranking but has been accessed recently
92+ will quickly have higher rank than a directory accessed frequently a
93+ long time ago.
94+
95+ Frecency is determined at runtime.
96+
97+ Common:
98+ When multiple directories match all queries, and they all have a common
99+ prefix, z will cd to the shortest matching directory, without regard to
100+ priority. This has been in effect, if undocumented, for quite some
101+ time, but should probably be configurable or reconsidered.
102+
103+ Tab Completion:
104+ z supports tab completion. After any number of arguments, press TAB to
105+ complete on directories that match each argument. Due to limitations of
106+ the completion implementations, only the last argument will be com-
107+ pleted in the shell.
108+
109+ Internally, z decides you've requested a completion if the last argu-
110+ ment passed is an absolute path to an existing directory. This may
111+ cause unexpected behavior if the last argument to z begins with /.
112+
113+ENVIRONMENT
114+ A function _z() is defined.
