in reply to Search array of file names in directory structure

If I'm following your spec, the easiest way to accomplish your goal is use a hash:
#!/usr/bin/perl -w use strict; use File::Find::Rule; use File::Basename; my @filelist = qw(1234567_3a_20101000.html 99877_b_20111111.html 9987 +7_c_20111111.html 99877_d_20111111.html 99877_e_20111111.html 99877_u +f_20111111.html 1234567_g_20101000.html 99877_h_20111111.html 99877 +_i_20111111.html 99877_j_20111111.html 99877_k_20111111.html 99877_ll +_20111111.html 1234567_pl_20101000.html 99877_qa_20111111.html 998 +77_rr_20111111.html 99877_sx_20111111.html 99877_xy_20111111.html 998 +77_nm_20111111.html); my %want; $want{$_}++ for @filelist; my $dir = '/var/www/files/'; my $find = File::Find::Rule ->file ->name(qr/\.html?$/) ->start( $dir ); my $f_count = 0; my @found_html; while ( defined ( my $html_document = $find->match ) ) { $f_count++; my $filenames = basename( $html_document ); push @found_html, $filenames if $want{$filenames}; }
