#cut for moonx

Version 0.2.2 behavior is documented here. The support record separates local verification from published MoonX behavior; moonx examples use registry releases.

Select fields or character positions from each line:

printf 'x,y,z\n' | moonx cli/cut -d, -f1,3
moonx cli/cut -c 1-4 fixed.txt

Options: -f LIST field list, -b LIST byte list, -c LIST character list (the latter two are identical under the fixed C-locale byte profile), -d CHAR field delimiter (default TAB), -s skip lines without the delimiter, and -z for NUL-delimited records. --complement selects positions outside the list; --output-delimiter=STRING joins selected fields or byte/character ranges. An empty output delimiter emits one NUL. Lists accept N, N-M, N-, and -M, separated by commas; output preserves input order. Overlapping ranges merge; adjacent explicitly listed ranges retain their output separator, so -b1-2,3-4 --output-delimiter='|' prints ab|cd.

An empty -d value selects NUL as the field delimiter. Non-delimited records pass through unchanged unless -s is present when the selection contains fields. If complement removes every field, GNU 9.11 handles undelimited input by blocks: a block containing field separators emits only record terminators, and an unterminated tail can be omitted. This behavior is retained for compatibility. When field and record delimiters are identical, field positions span the input file rather than resetting at every delimiter; a final delimiter terminates the last field without creating an extra empty field. Delimiter and -s options are rejected outside field mode.

#Standalone metadata

Standalone --version prints exactly cut 0.2.2 followed by one newline. Standalone --help starts with Usage: cut, lists both metadata options, and ends with a newline. Both write to stdout, leave stdin unread, and exit with status 0. Exact-version publication and verification remain recorded separately in the support record.
