Perl:用File::Basename来获取文件…_综合

以下内容来自Code Snippets。Perl的File::Basename 模块

File::Basename 模块被用来析取文件路径中的目录，文件名以及后缀。我的这个简单例子演示了如何获取文件后缀。

至于详细用法，用perldoc File::Basename命令查看。

DESCRIPTION

These routines allow you to parse file specifications into

useful pieces using the syntax of different operating sys-

tems.

#!/usr/bin/perl

use strict;

use File::Basename;

use CGI qw/:standard/;

#if running as a CGI application

#use CGI::Carp qw/fatalsToBrowser/;

# uncomment for debugging onlyprint header,start_html;

# if running as a CGI application

my $dir = '/home/username/public_html';

opendir(DIRHANDLE,$dir) or die "Can't open $dir: $!";

my @filenames = sort readdir(DIRHANDLE);

close(DIRHANDLE);

foreach my $file (@filenames) {

my(undef, undef, $ftype) = fileparse($file,qr"\..*");

print "$ftype\n";

}

print end_html; #if running as a CGI application
