whiff - like which, but finds the first of all the given alternatives
whiff <command ... >
which is a useful utility, found on most unix systems. It gives you the absolute path for the first occurance of a program in your path. Unfortunately, it does two stupid things: first, if it can't find one, it prints an error message to stdout; secondly, if you give it multiple arguments, it assumes you want one line per argument, each like calling which individually.
whiff assumes that all the arguments form a best-first list of alternatives, and only prints the path to the first alternative found in the path. If none is found, it prints an error (to stderr!) and exits with an error code.
