如何.eml迭代文件目录？

nicholas@mordor:~$ 
nicholas@mordor:~$ mail -f foomail/foo.eml 
"/home/nicholas/foomail/foo.eml": 0 messages
nicholas@mordor:~$

然而，我希望看到一个可供选择的列表。

你不能，EML 格式是不是受支持的本地邮箱格式由 GNU Mailutils ...但是，显然 MBOX 格式是。

幸运的是从 EML 到 MBOX 的转换很容易，这正是您应该考虑的。

为了证明这一点，我用了这个样本 EML... 所以，

$ head *.eml

...并尝试用mailutils（不起作用)：

$ mail -V

$
$ 
$ mail --file *.eml
mail: -f requires at most one command line argument
$ 
$ 
$ mail --file 1.eml
"/home/ubuntu/test/dir/1.eml": 0 messages

...现在让我们将这 3 条 EML 消息转换为一个 MBOX 文件：

$ for e in *.eml
  do
    date +"From - %a %b %d %H:%M:%S %Y" >> file.mbox
    cat "$e" >> file.mbox
    echo >> file.mbox
    done
$ 
$ 
$ ls -lh
total 20K
