This will break anyway in the future. GNU coreutils changed the 'wording' of the --version output a couple of times in the past. ARC...ARC... the ARC case for GNU coreutils nor the manpages specify a specific wording 'syntax'. Sounds like from an ARC perspective this does not matter. >> If so then I wonder why we are even shipping the GNU >> ones. > > Because that's what many users and applications expect.
