* `path` — Manage the contents of `PATH` conveniently
* `paz` — Print given arguments separated by NULL chars
* `pd` — Change to the argument’s parent directory
+* `readv` — Print names and values from `read` calls to `stderr`
* `readz` — Alias for `read -d '' -r`
* `scr` — Create a temporary directory and change into it
* `sd` — Switch to a sibling directory
