    Is this from an array or the filesystem?

    If it's the filesystem, and it's unix, try:

    ls ???1107*
    if it's the filesystem, and it's Windows, try:
    dir ???1107*.*
    if it's an array, try:
    my @filtered_files = grep { /^...1107/ } @files;
      Hi, Below mentioned script is filter and display all files whose file type is 33188.
      #!/usr/bin/perl -w use strict; use File::stat; sub dodir { opendir(DIR,$_[0]) or die "Couldn't open $_[0] directory $!"; my $dir=$_[0]; print "\n Directory name is $dir"; if ( $dir !~ /\/$/ ) { $dir .= "/"; } my @List=readdir(DIR); closedir(DIR); splice(@List,0,2); foreach my $file (@List) { $file = $dir.$file; if( -d $file) { dodir($file); } elsif (stat($file)->mode == 33188 ) { print "\n File $file is pre +sent in $dir"; print "\n File type: ",stat($file)->mode; } } } my $dir_name="/home"; if ( -d $dir_name) { dodir($dir_name); }

    Sorry, my english isnt so good. well , let me try to explain it on a other way. Ive got a tool, which read files from a server. those files have specific filenames. The differences of the filenames are the date, which is in the name included. like file a) xyz11072002.xyz file b) zyx11072002.xyz file c) xyz01012002.xyz Now i just want to filter the files, which include the date of yesterday or a other special day( 11.07.2002). All these files are saved on a extern server. And i want to filter the files bevor i save it , for ex. in an array or an any list. I hope i could explain it.. thanks for ur help greetz IceZero
