# Zsh-z maintains a jump-list of the directories you actually use.
|
||
|
|
#
|
||
|
|
# INSTALL:
|
||
|
|
# * put something like this in your .zshrc:
|
||
|
|
# source /path/to/zsh-z.plugin.zsh
|
||
|
|
# * cd around for a while to build up the database
|
||
|
|
#
|
||
|
|
# USAGE:
|
||
|
|
# * z foo cd to the most frecent directory matching foo
|
||
|
|
# * z foo bar cd to the most frecent directory matching both foo and bar
|
||
|
|
# (e.g. /foo/bat/bar/quux)
|
||
|
|
# * z -r foo cd to the highest ranked directory matching foo
|
||
|
|
# * z -t foo cd to most recently accessed directory matching foo
|
||
|
|
# * z -l foo List matches instead of changing directories
|
||
|
|
# * z -e foo Echo the best match without changing directories
|
||
|
|
# * z -c foo Restrict matches to subdirectories of PWD
|
||
|
|
# * z -x Remove a directory (default: PWD) from the database
|
||
|
|
# * z -xR Remove a directory (default: PWD) and its subdirectories from
|
||
|
|
# the database
|
||
|
|
#
|
||
|
|
# ENVIRONMENT VARIABLES:
|
||
|
|
#
|
||
|
|
# ZSHZ_CASE -> if `ignore', pattern matching is case-insensitive; if `smart',
|
||
|
|
# pattern matching is case-insensitive only when the pattern is all
|
||
|
|
# lowercase
|
||
|
|
# ZSHZ_CD -> the directory-changing command that is used (default: builtin cd)
|
||
|
|
# ZSHZ_CMD -> name of command (default: z)
|
||
|
|
# ZSHZ_COMPLETION -> completion method (default: 'frecent'; 'legacy' for
|
||
|
|
# alphabetic sorting)
|
||
|
|
# ZSHZ_DATA -> name of datafile (default: ~/.z)
|
||
|
|
# ZSHZ_EXCLUDE_DIRS -> array of directories to exclude from your database
|
||
|
|
# (default: empty)
|
||
|
|
# ZSHZ_KEEP_DIRS -> array of directories that should not be removed from the
|
||
|
|
# database, even if they are not currently available (default: empty)
|
||
|
|
# ZSHZ_MAX_SCORE -> maximum combined score the database entries can have
|
||
|
|
# before beginning to age (default: 9000)
|
||
|
|
# ZSHZ_NO_RESOLVE_SYMLINKS -> '1' prevents symlink resolution
|
||
|
|
# ZSHZ_OWNER -> your username (if you want use Zsh-z while using sudo -s)
|
||
|
|
# ZSHZ_UNCOMMON -> if 1, do not jump to "common directories," but rather drop
|
||
|
|
# subdirectories based on what the search string was (default: 0)
