我的linux在看mail時要如何看下一頁？

[bigmichael]

我的linux主機，有一個帳號收到了一百多封信。
我要把不要的信先刪除！
我要以看誰寄來的來判斷。
但是我打mail如下：

[b@linux b]$ mail
Mail version 8.1 6/6/93. Type ? for help.
"/var/spool/mail/b": 132 messages 132 unread

下面還有一百多封信。我要如何讓它換頁讓我直接看第21封信到40封信呢？
因為之後的信，不知如何換頁來看誰寄來的信，要一封一封的點開來看，不知道要點到什摸時候！

教教我嘛！

按z就換頁
z+下一頁
z-上一頁
自己可以先看看 mail 的man page 吧...裡面有提到
