利用~/.netrc文件自动ftp下载文件 (当天或昨天的tomcat日志)

home目录中添加文件.netrc,内容如下：

#download files begin with test under user david's home

machine 172.16.100.30 login david password 3287

macdef init

binary

prompt

!clear

mget test*

!clear

bye

#get the log of yesterday:

#echo "catalina.`date --date='1 days ago' +%Y-%m-%d `.log" | ftp www.kseeker.com

#download file specified by the second arg (the log filename)

machine www.kseeker.com login david password pass92342@#$@**(89

macdef init

binary

prompt

cd /home/tomcat/logs

mget $2

bye

注意：bye后要有一空行,.netrc文件的属性须是600,

可以使用这个命令下载172.16.100.30上面/home/david/目录test开头的文件：%ftp 172.16.100.30

可以使用这个命令来下载服务器上昨天的tomcat日志（文件名如: catalina.2007-01-24.log）：

%echo "catalina.`date --date='1 days ago' +%Y-%m-%d `.log" | ftp www.kseeker.com
