How can I include a literal '+' (plus character) in my search?
By remembering that this is a regex search. How do you quote special characters
in regexes? Answer: With a '\'.
I am surely dumb, but whatever and how many '\' are used
the '+' is always returned as a ' ' in the reply.
So the specific example will be appreciated,
as a single quoting usually works in regexes
$ cd /etc/setup
$ zcat gcc-g++.lst.gz |grep -P "g\+\+"
usr/bin/g++.exe
usr/bin/i686-pc-cygwin-g++.exe
usr/share/man/man1/g++.1.gz
Is something "sanitizing" the query on server side to avoid
nasty surprise ?
$ zcat gcc-g++.lst.gz |grep -P "g++" |wc -l
