chosse selected files and delete rest

namishtiwari has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks, Here is my piece of code--

#!/usr/bin/perl
use Net::FTP;
use Archive::Zip;
use IO::File ;
    
print "Retrieving file from log.abc.com...\n";
$loginip='123.678.90.18';
$loginid='nkt123';
$loginpaswd='12345678';
($sec,$min,$hour,$mday,$mon,$year)=(localtime(time))[0,1,2,3,4,5];
$time_stamp= "_" . (1900+$year) . "_" . ($mon+1) . "_" . ($mday) . "_"
+ . $hour . "_" . $min . "_". $sec;
printf "time stamp = $time_stamp\n";


unless(-d "temp")
{
mkdir("temp");
}
if( -d "temp")
{
chdir("temp");
}

$ftp = Net::FTP->new(($loginip), Debug => 0)
or die "Cannot connect to log.abc.com: $@ \n";

$ftp->login($loginid,$loginpaswd)
or die "Cannot login ", $ftp->message;

$source_dir="/nt/logs/nali05/";

$ftp->cwd($source_dir)
or die "Cannot change working directory ", $ftp->message;


$ftp->binary || die "Unable to set mode to binary. ", $ftp->message;

@list=$ftp->ls();
printf "list = \n";
print @list;
foreach $file (@list)
{
$ftp->get($file) or die "get failed ", $ftp->message;
my $zipname = $file;
my $destinationDirectory = 'C:\Perl Script\temp';
my $zip = Archive::Zip->new($zipname);
foreach my $member ($zip->members)
{
    next if $member->isDirectory;
    (my $extractName = $member->fileName) =~ s{.*/}{};
    $member->extractToFileNamed(
      "$destinationDirectory/$extractName");
}


#rename($file,"${file}_${time_stamp}");
$ftp->delete ($file) or die "rm -rf failed ", $ftp->message;
}
#}
$ftp->quit;

I am getting the files from ftp site and the files that are zipped ones. I am able to extract them also in the same folder. I need little help in--- The unzipped files which i got, i only need few of them not all. The format of the filename is like this---

risk_14Jul09_16_10_48.log
web_14Jul09_16_10_48.log
[download]

I get so many files files when i unzip thme , this is just a sample. In these two files i want the files which contains web in that and delete the rest from the folder. And one more help i need is this-- We get 4-5 log files for a day with the fromat above. There will be files older than today also, i want to run my script for today's logs only. Thanks NT

...or, for your pattern match match based solution, why not utilize the fact that unlink takes a list viz (also untested:-): `unlink grep { -f $_ && ! /$pattern/ } glob "$Directory/*";` [download] A user level that continues to overstate my experience :-))	[reply] [d/l]
