#cat for moonx

Version 0.2.1 behavior is documented here. The support record separates local verification from published MoonX behavior; moonx examples use registry releases.

Concatenate files or stdin to stdout, byte-transparently:

moonx cli/cat a.txt b.txt
printf '\x00\xff' | moonx cli/cat | moonx cli/xxd -p   # 00ff

Bytes pass through unmodified when no formatting option is selected. -n and -b number lines, -s squeezes repeated blank lines, and -A, -e, -E, -t, -T, and -v expose the common GNU visible-byte forms. Formatting state is continuous across file operands, including an unterminated line at a file boundary. Use - (or no argument) to read stdin. -u/--unbuffered is accepted as the GNU compatibility no-op; MoonBit writes through its byte stream without an additional user-space buffer.

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 cat 0.2.1 followed by one newline. Standalone --help starts with Usage: cat, 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.
