Top Forums Shell Programming and Scripting Extended grep not matching some patterns Post 303009906 by Don Cragun on Thursday 21st of December 2017 10:41:53 PM

Noting that \w is not a "standard" feature in an extended regular expression and noting that on systems where \w is requesting a match to a word, there is no word between the = and the ' in subscriptions=' and that there is no word between the = and the " in handler="; what additional output were you hoping to get?

What operating system are you using?

What shell are you using?

Is this a homework assignment?

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
