I have a script that is supposed to pull a few files from a remote server daily. I am having a problem with the the file names since they have the timestamp at the end. I want to be able to use wildcards for the last part of each file and the first characters are known. This is what I have now. This only trys to get a file called 0 and 1. I can't find a way to match "IRP_*" to find a file called "IRP_0304041213"

use Net::SFTP::Foreign;
use Switch;
use Net::SFTP::Foreign::Constants qw(:error);
my $leap_year = 0;
my $inter_server = "0.0.0.0";
my $ai_user = "guest";
my $ai_pass = "password";  #Want to encrypt these in script
my $ai_dir = "";
my $ai_dest_day = "/APP/FTP/Daily/Input";
my $ai_dest_mon = "/APP/FTP/Monthly/Input";
my @ai_files_day = qw{IRP_ trigextract_ VRP_};
my @ai_files_mon = qw{snapshot_ };
my ($sec, $min, $hour, $day, $month, $year) = localtime;

    my $sftp = Net::SFTP::Foreign->new($inter_server, user => "$ai_use
+r", password => "$ai_pass"); # Add 'more => '-v'' debug
    $sftp->error and warn "SFTP connection failed: " . $sftp->error;
    print ("Connected to $inter_server($inter_server)\n");
    print "Trying to login to $inter_server \n";
    print ("Login was successful.\n");

    foreach my $file (@ai_files_day){  #daily list

    our $newerr = "0";

    $file .= "$yesterday";
    #$mfile .= "mod_yester";

    $file = $sftp->glob("${file}*");
     print ("$file\n"); #This is for debug.

    $sftp->mget("$ai_dir/${file}", "$ai_dest_day/${file}") or $newerr=
+1;
      print "Failed to retreive file $file : $!\n" if $newerr==1;
        next if $newerr;

    print ("Retreiving file $file ...... Success!\n");

       if ($newerr != 1){
        $sftp->remove("$ai_dir/${file}*")or $newerr=3;
            print "Deleting file $file ...... Failed!: $!\n" if $newer
+r==3;

            print ("Deleting file $file ...... Success!\n");
        }
    $newerr = "0";
    }

Any suggestions for something to try to make this work?
