# INSTALL:
|
|
# * put something like this in your .bashrc/.zshrc:
|
|
# . /path/to/z.sh
|
|
# * cd around for a while to build up the db
|
|
# * PROFIT!!
|
|
# * optionally:
|
|
# set $_Z_CMD in .bashrc/.zshrc to change the command (default z).
|
|
# set $_Z_DATA in .bashrc/.zshrc to change the datafile (default ~/.z).
|
|
# set $_Z_MAX_SCORE lower to age entries out faster (default 9000).
|
|
# set $_Z_NO_RESOLVE_SYMLINKS to prevent symlink resolution.
|
|
# set $_Z_NO_PROMPT_COMMAND if you're handling PROMPT_COMMAND yourself.
|

# set $_Z_EXCLUDE_DIRS to an array of directories to exclude.
|
|
# set $_Z_OWNER to your username if you want use z while sudo with $HOME kept
|

# USE:
|
|
# * z foo # cd to most frecent dir matching foo

# * z -e foo # echo the best match, don't cd
