#which

Version 0.1.2. See the support record for release evidence.

Find executable files using the caller's PATH:

moonx cli/which sh
moonx cli/which -a sh
moonx cli/which -s ./tool

-a/--all prints all matching executable regular files. Without it, only the first match is printed. -s/--silent suppresses both normal and missing-command output; status is 1 if any operand is missing. Path operands are checked directly. POSIX requires executable access and treats backslash as a filename character. Empty PATH entries mean the current directory.

Windows uses semicolon-separated PATH and PATHEXT (default .COM;.EXE;.BAT;.CMD) to resolve executable suffixes. Files are inspected, never launched during lookup. Shell aliases and functions are outside this command's scope. --help and --version are available.

#Standalone metadata

Standalone --version prints exactly which 0.1.2 followed by one newline. Standalone --help starts with Usage: which, 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.
