perl 取出目录中的所有文件并存入文件中

 我们可以把从目录中取出的所有文件打印到文件中：

#!/usr/bin/perl -wT

use File::Copy;

use strict;

print "取文件,请输入文件路径:";

chomp(my $path = <STDIN>);

opendir DIR, $path;

my @dir = readdir DIR;

closedir DIR;

foreach my $file (@dir){

open OUTFILE,">>test.info";

print OUTFILE "$file\n";    //改变了输出句柄

close OUTFILE;

}
