printf is new enough that shells that support it most likely also support type. At any rate, I would assume that this might be a close enough approximation to what you are asking for, in that it would only give false negatives: case `(type printf) 2>/dev/null` in *built*in*) echo builtin ;; *) echo external or missing ;; esac My only concern is whether it would work reliably in MSYS, since Windows provides a 'type.exe' utility that behaves more like cat; but my understanding is that running ./configure on MSYS uses bash, where type and printf are builtins, so I think it will work there, too. - -- Life is short - so eat dessert first!
