#uniq for moonx
Unpublished candidate 0.2.3 behavior is documented here. The
support record separates local verification from
published MoonX behavior; moonx examples use registry releases.
The candidate retains byte views for current records/keys and batches output
through core 0.8.2. A synchronous batch visitor processes records until an output
flush is needed; unmodified keys reuse the original view. Group separators and
duplicate-selection rules are unchanged.
Filter adjacent repeated lines (pipe through sort first for global dedup):
sort words.txt | moonx cli/uniq
printf 'a\na\nb\n' | moonx cli/uniq -cOptions: -c prefixes occurrence counts in the GNU seven-column form, -d
selects repeated records, -u selects unrepeated records, and -i folds ASCII
case. -f/--skip-fields skips blank-delimited fields before
-s/--skip-chars; -w/--check-chars limits the compared suffix. -z or
--zero-terminated switches record input and output to NUL. Selection uses
the fixed LC_ALL=C byte profile, including malformed byte input.
-D or --all-repeated[=METHOD] prints every member of repeated groups,
omitting singleton groups. The default method none adds no separator;
prepend inserts a record separator before each output group and separate
inserts one only between output groups. A later bare -D resets the method to
none. With -u -D, every member except the last in each repeated group is
printed; -d -u without -D prints nothing.
--group[=METHOD] prints every input record and separates adjacent groups.
The default separate inserts separators only between groups. prepend,
append, and both also select separators at the beginning, end, or both.
Empty input prints no separators. Methods accept unambiguous abbreviations;
the last specified method is used. --group conflicts with -c, -d, -D,
and -u; -c also conflicts with -D. These conflicts are rejected before
input or output. Group output retains each original record and streams with
only one pending record and comparison key retained.
With no file operand, the command silently reads stdin until EOF, matching the
upstream terminal, pipe, redirection, and explicit - behavior.
#Standalone metadata
Standalone --version prints exactly uniq 0.2.3 followed by one
newline. Standalone --help starts with Usage: uniq, 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.
