The rank of each entry is incremented every time it is accessed. When +the sum of ranks is over 9000, all ranks are multiplied by 0.99. Entries with a +rank lower than 1 are forgotten. +.SS +Frecency: +Frecency is a portmanteau of 'recent' and 'frequency'. It is a weighted rank +that depends on how often and how recently something occurred. As far as I +know, Mozilla came up with the term. +.P +To \fBz\fR, 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. +.P +Frecency is determined at runtime. +.SS +Common: +When multiple directories match all queries, and they all have a common prefix, +\fBz\fR 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. +.SS +Tab Completion: +\fBz\fR 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 completed in the +shell. +.P +Internally, \fBz\fR decides you've requested a completion if the last argument +passed is an absolute path to an existing directory. This may cause unexpected +behavior if the last argument to \fBz\fR begins with \fB/\fR. +.SH +ENVIRONMENT +A function \fB_z()\fR is defined. +.P +The contents of the variable \fB$_Z_CMD\fR is aliased to \fB_z 2>&1\fR. If not +set, \fB$_Z_CMD\fR defaults to \fBz\fR. +.P +The environment variable \fB$_Z_DATA\fR can be used to control the datafile +location. If it is not defined, the location defaults to \fB$HOME/.z\fR. +.P +The environment variable \fB$_Z_NO_RESOLVE_SYMLINKS\fR can be set to prevent +resolving of symlinks. If it is not set, symbolic links will be resolved when +added to the datafile. +.P +In bash, \fBz\fR appends a command to the \fBPROMPT_COMMAND\fR environment +variable to maintain its database. In zsh, \fBz\fR appends a function +\fB_z_precmd\fR to the \fBprecmd_functions\fR array. +.P +The environment variable \fB$_Z_NO_PROMPT_COMMAND\fR can be set if you want to +handle \fBPROMPT_COMMAND\fR or \fBprecmd\fR yourself. +.P +The environment variable \fB$_Z_EXCLUDE_DIRS\fR can be set to an array of +directory trees to exclude from tracking. \fB$HOME\fR is always excluded. +Directories must be full paths without trailing slashes. +.P +The environment variable \fB$_Z_OWNER\fR can be set to your username, to +allow usage of \fBz\fR when your sudo environment keeps \fB$HOME\fR set. +.SH +FILES +Data is stored in \fB$HOME/.z\fR. This can be overridden by setting the +\fB$_Z_DATA\fR environment variable. When initialized, \fBz\fR will raise an +error if this path is a directory, and not function correctly. +.P +A man page (\fBz.1\fR) is provided. +.SH +SEE ALSO +regex(7), pushd, popd, autojump, cdargs +.P +Please file bugs at https://github.com/rupa/z/ |
