[Solved] perl and grep: get a script to look at more then one file
hi guys

i have this very messy script, that looks in /var/log/messages.all for an error and reports if it finds the key works

how can i get it to look at more then one file, i.e /var/log/message.all *

so it looks in old logs as well

thanks

Code:
exit 0 if (isRenderNode(hostname));
my $PROG     = 'nvrm';
my $xorglog = '/var/log/messages.all';
my $techuser = 'caston|sutton|copdock';




if ($DNHOST !~($techuser)){
if (-e "$xorglog" ) {
    open my $xorg_log, $xorglog or die "$PROG: can't open $xorglog: $!\n";
    my @xorglog = <$xorg_log>;
    close $xorg_log;
    if (grep  { /NVRM: Xid/ } @xorglog) {
        print " Serial Tag: ";
    print `cat /tools/SITE/etc/cfg/systems/systems | grep $DNHOST | cut -d , -f 9 `;
    print " Room Number: ";
          print `cat /tools/SITE/etc/cfg/systems/systems | grep $DNHOST | cut -d , -f 3 `;
    print `dnsu dnhinv | grep -i Graphics| cut -d : -f 2\n `;
    print `dnsu dnhinv | grep -i BIOS | cut -d ] -f 2 \n`;
    print `cat $xorglog | grep "NVRM: Xid"`;
        }
   # XXX more... 
}
}

zfgrep

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME

     zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files

SYNOPSIS

     zgrep [grep-flags] [--] pattern [files ...]

     zegrep [grep-flags] [--] pattern [file ...]

     zfgrep [grep-flags] [--] pattern [file ...]

DESCRIPTION

     zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1).

     The grep-flags and pattern arguments are passed on to grep(1).  If an -e flag is found in the grep-flags, zgrep will not look for a pattern
     argument.

     zegrep calls egrep(1), while zfgrep calls fgrep(1).

EXIT STATUS

     In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.

SEE ALSO

     egrep(1), fgrep(1), grep(1), gzip(1), zcat(1)
