Thank you. But on the "POSIX Extended Regular Expression Syntax" page the escape sequence \w is very well listed:
I should have explained this more thoroughly. I did not say that POSIX does not support \w at all. What I said was:
I suspected that Perl would support the escape sequence \w inside a [] character set, but POSIX extended might not. The tests I ran affirmed those suspicions.
POSIX extended supports \w, but NOT inside a [] character set. For POSIX extended, the regex [\w\-\.~/]+ is the same as [w\-\.~/]+. Inside of [], POSIX extended sees \w as a literal "w". You can test this yourself if you have an up-to-date version of the egrep shell command. |+| M a r k |+| Mark Stallard Business Application Services Global Business Services Information Technology Raytheon Company (business) 978-436-8487 (cell) 617-331-5443 stallard@raytheon.com 880 Technology Drive Billerica, MA 01821 www.raytheon.com This message contains information that may be confidential and privileged.
