I have a Unix script right now that I'm converting to a Perl script (going to Microsoft). The unix script looks at a text file using grep -v and grep and writes to two seperate files depending on the outcome. The contents of the file that is getting grepped could look something like this:

order_item : CKFH6-05 : INVALID KEY ID : CKFH6-05
order_item : CKFH6-05 : *** OK *** : CKFH6-05

The grep from the unix script looked like this: 
foreach i ('ls -d APPL_RMKS_RCV* ')
   grep -v 'NOT|INVALID|MUST|ERROR' $i | grep - >> ${good_ones}
   grep 'NOT|INVALID|MUST|ERROR' $i | grep - >> ${bad_ones}
end

To this point, for the Perl script I have: 
foreach $file(@file){
open(MYFILE, $file[$i]) or die qq(Cannot open $file[$i]\n);
    my $line = <MYFILE>;
    while ($line ne "") {
        #******* do grep here *******#
        }
    }    
    $i++;
}

What would be the equivalent in Perl for the grep in my unix script? Namely the grep -v. Thank you.
