Re: Cygwin man does not recognise PerlRE ?

Iâm curious: what sort of incantations do you frequently give to man which involve REs?

Maybe Iâm just too old-school, but I wasnât aware that modern man programs even supported REs.  Back when I was a boy, we said âman -k whatsitâ and we liked it! :)

I think if I wanted to grep man pages with Perl syntax, Iâd say

   grep -PRsl whatsit /usr/share/man

Poking around on machines near me, I see Lucifrediâs version of man â which doesnât seem to support regexes â on OS X 10.10, FreeBSD 10.1, and CentOS 5.  Apparently RHEL moved to man-db in EL6 or EL7, since itâs on an EL7 box nearby.
