Jump to most frecent directory matching pattern

z tracks your most used directories and allows you to jump to them with minimal keystrokes. It uses "frecency" - a combination of frequency and recency - to rank directories.
As you navigate with cd, z learns which directories you visit most. Typing z foo jumps to the most frecent directory containing "foo" in its path. Multiple arguments are matched in order: z foo bar matches paths containing "foo" followed by "bar".
The database is stored in ~/.z by default and is updated automatically when changing directories (via a shell hook).

-c

Restrict matches to subdirectories of current directory

Show help

List matches instead of jumping

Match by rank only (most accessed)

Match by recency only (most recent)

Requires shell integration. Add source /path/to/z.sh to your shell profile (.bashrc, .zshrc) for it to track directories.
New installations start with an empty database. It takes time for z to learn your patterns.
Matching is case-insensitive by default but can be configured.
Similar tools exist: zoxide, autojump, fasd offer comparable functionality with different features.
