But BSD true doesn&#x27;t support --version, how are you going to check your version of true without a locale-aware version string (and yes, gnu true is locale-aware, and contains 2k of strings including 48 encoding names and 36 format strings — 10 of which are duplicates, and for some reason refers to the SHA2 utilities)<p>(I dimly remember an essay about similar issue in a similar mainframe command (maybe in JCL?) taking a bunch of revisions to actually get right?)
