Hi All,

I have the following code. Each key in %logfiles looks similar to HELog_fpltesthc.log.3.gz. When I try to use the split fuction on the keys it fails with the error below? I am new to perl and maybe this is not possible. Does anyone see the error of my way?

foreach $log ( sort keys %logfiles ) {
    foreach ( @surl ) {
        $urlp = $_ . 'hc';
        if ( $log =~ /[.]/ && $log !~ /^[.]/ ) {
            @slog = split( '.', $log );
            #$slog[0] =~ s/HELog_//g;
            print $slog[0];
            #if ( $slog[0] eq $urlp ) {
                #push @logfiles, $log;
            #}
        }
    }
}

The line that is erroring out is: print $slog[0];

Apparently the split is failing.
