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.

moonx cli/paste -s -d, nums.txt # serial: one output line per file
Options: -d LIST delimiter characters cycled between columns (defaultTAB; \b, \f, \n, \r, \t, \v, \0 for empty, and \\ areunderstood), -s serialmode, and -z for NUL-delimited input and output records. Repeated -operands consume successive records from the same stdin stream. An empty delimiter list selects one empty delimiter, whilea trailing unescaped backslash is rejected before any input is consumed.Delimiter cycling is over raw bytes, matching LC_ALL=C.
With no file operand, the command silently reads stdin until EOF, matching theupstream terminal, pipe, redirection, and explicit - behavior.
