Good post... a minor nit, though. You can use + in Vim regexes, but you have to precede it with a backslash. Vim regexes and Perl regexes are not the same (knowing when to use backslashes often throws me off), but I think they're much more similar than they are different.

    OK so I lied (it was just a little one!) It really uses the abortive GNU regex syntax that is just different enough from Perl to s!+t you if you really know perl REs.....it is like grep. My usual greps are called re and re! linked into /usr/bin. They look like:

    [root@devel3 root]# cat /usr/bin/re #!/usr/bin/perl die "Usage re [RE]\nFull Perl grep on STDIN\n" unless @ARGV == 1; my $re = qr/$ARGV[0]/; while(<STDIN>) { print if m/$re/; } [root@devel3 root]# cat /usr/bin/re! #!/usr/bin/perl die "Usage re [RE]\nFull Perl grep on STDIN\n" unless @ARGV == 1; my $re = qr/$ARGV[0]/; while(<STDIN>) { print if ! m/$re/; } [root@devel3 root]# cat some.file | re "some perl re"

    cheers
