NAME
|
||||
z - jump around
|
||||
|
||||
SYNOPSIS
|
||||
z [-chlrt] [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'
|
||||
directory that matches ALL of the regexes given on the command line.
|
||||
|
||||
OPTIONS
|
||||
-c restrict matches to subdirectories of the current directory.
|
||||
|
||||
-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:
|
||||
Put something like this in your $HOME/.bashrc or $HOME/.zshrc:
|
||||
|
||||
. /path/to/z.sh
|
||||
|
||||
cd around for a while to build up the db.
|
||||
|
||||
PROFIT!!
|
||||
|
||||
Optionally:
|
||||
Set $_Z_CMD to change the command name (default z).
|
||||
Set $_Z_DATA to change the datafile (default $HOME/.z).
|
||||
Set $_Z_NO_RESOLVE_SYMLINKS to prevent symlink resolution.
|
||||
Set $_Z_NO_PROMPT_COMMAND to handle PROMPT_COMMAND/precmd your-
|
||||
self.
|
||||
Set $_Z_EXCLUDE_DIRS to an array of directories to exclude.
|
||||
(These settings should go in .bashrc/.zshrc before the lines
|
||||
added above.)
|
||||
Install the provided man page z.1 somewhere like
|
||||
/usr/local/man/man1.
|
||||
|
||||
Aging:
|
||||
The rank of directories maintained by z undergoes aging based on a sim-
|
||||
ple formula. The rank of each entry is incremented every time it is
|
||||
accessed. When the sum of ranks is greater than 6000, all ranks are
|
||||
multiplied by 0.99. Entries with a rank lower than 1 are forgotten.
|
||||
|
||||
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.
|
||||
|
||||
To 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.
|
||||
|
||||
Frecency is determined at runtime.
|
||||
|
||||
Common:
|
||||
When multiple directories match all queries, and they all have a common
|
||||
prefix, z will cd to the shortest matching directory, without regard to
|
||||
priority. This has been in effect, if undocumented, for quite some
|
||||
time, but should probably be configurable or reconsidered.
|
||||
|
||||
Tab Completion:
|
||||
z supports tab completion. After any number of arguments, press TAB to
|
||||
complete on directories that match each argument. Due to limitations of
|
||||
the completion implementations, only the last argument will be com-
|
||||
pleted in the shell.
|
||||
|
||||
Internally, z decides you've requested a completion if the last argu-
|
||||
ment passed is an absolute path to an existing directory. This may
|
||||
cause unexpected behavior if the last argument to z begins with /.
|
||||
|
||||
ENVIRONMENT
|
||||
A function _z() is defined.
|
||||
|
||||
The contents of the variable $_Z_CMD is aliased to _z 2>&1. If not set,
|
||||
$_Z_CMD defaults to z.
|
||||
|
||||
The environment variable $_Z_DATA can be used to control the datafile
|
||||
location. If it is not defined, the location defaults to $HOME/.z.
|
||||
|
||||
The environment variable $_Z_NO_RESOLVE_SYMLINKS can be set to prevent
|
||||
resolving of symlinks. If it is not set, symbolic links will be
|
||||
resolved when added to the datafile.
|
||||
|
||||
In bash, z prepends a command to the PROMPT_COMMAND environment vari-
|
||||
able to maintain its database. In zsh, z appends a function _z_precmd
|
||||
to the precmd_functions array.
|
||||
|
||||
The environment variable $_Z_NO_PROMPT_COMMAND can be set if you want
|
||||
to handle PROMPT_COMMAND or precmd yourself.
|
||||
|
||||
The environment variable $_Z_EXCLUDE_DIRS can be set to an array of
|
||||
directories to exclude from tracking. $HOME is always excluded. Direc-
|
||||
tories must be full paths without trailing slashes.
|
||||
|
||||
FILES
|
||||
Data is stored in $HOME/.z. This can be overridden by setting the
|
||||
$_Z_DATA environment variable. When initialized, z will raise an error
|
||||
if this path is a directory, and not function correctly.
|
||||
|
||||
A man page (z.1) is provided.
