Defaults are --key=token --result=filenames --separator=space -F, --frequency=FREQ find tokens that occur FREQ times, where FREQ is a range expressed as `N..M'. If N is omitted, it defaults to 1, if M is omitted it defaults to MAX_USHRT -a, --ambiguous=LEN find tokens whose names are ambiguous for LEN chars -x, --hex only find numbers expressed as hexadecimal -d, --decimal only find numbers expressed as decimal -o, --octal only find numbers expressed as octal By default, searches match numbers of any radix. --help display this help and exit --version output version information and exit REPORTING BUGS
