perl Net::FTP文件上传下载

#!/usr/bin/perl

use Net::FTP;

( $day, $mon, $year) = (localtime)[3..5];
$mon=$mon+1;
$year=$year+1900;
$host_ip=`ifconfig eth0 |grep "inet addr" |cut -d: -f2 |cut -d" " -f1`;
chomp($host_ip);
$localfile="$host_ip&$year$mon$day.txt";
$ftp=Net::FTP->new("host_ip", Debug=>1)
        or die "Cannot connect to host_ip:$@";
$ftp->login("ftpname",'mima')
        or die "Cannot login",$ftp->message;
$ftp->cwd("/var/ftp/pub")
        or die "Cannot change working directory", $ftp->message;
$ftp->put ("$localfile")
        or die die "put failed",$ftp->message;
$ftp-quit;
 

在十几号的时候写了上面那个脚本，发现到10号前，文件日期出了问题，悲催，因为我的python脚本的文件日志格式是20130105，上面的是201315，没办法用shell修改下吧

#!/usr/bin/perl

use Net::FTP;
$time=`date +%Y%m%d`;
chomp($time);
$host_ip=`ifconfig eth0 |grep "inet addr" |cut -d: -f2 |cut -d" " -f1`;
chomp($host_ip);
$localfile="$host_ip&$time.txt";
$ftp=Net::FTP->new("host_ip(ftp服务器IP)", Debug=>1)
        or die "Cannot connect to host_ip:$@";
$ftp->login("用户",'密码')
        or die "Cannot login",$ftp->message;
$ftp->cwd("/var/ftp/pub")
        or die "Cannot change working directory", $ftp->message;
$ftp->put ("$localfile")
        or die die "put failed",$ftp->message;
$ftp-quit;
