Support note (2026-09-05): this README is supplementary. The support record is the only capability authority; it separates native compatibility evidence from Wasm policy and smoke evidence. Options mentioned here but not promoted in that record are not compatibility guarantees.
Remove directory components from path operands. Supports -a/--multiple,-s/--suffix, and NUL-delimited output with -z.
An empty operand produces an empty record; repeated separators and root pathsfollow the coreutils byte-oriented path rules.
