I'm not sure whether it can meaningfully serve this function in the specific case given, but generally - particularly, IIRC, for GNU programs - a standalone '-' means something like "treat the data you receive from stdin as if it were the contents of an input file". That wouldn't seem to fit too well with the use of the '-T' option, which appears to mean "read the list of input filenames from the specified file", but it's what I'd normally expect that syntax to mean. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
