我在用杂种狗,我的收件箱中有一封邮件,其中包含大约 1000 个附件,其中约 50% 是 .jpg 文件。我想将所有这些附件保存到指定目录中,而不保留其他附件。
是否可以通过几个按键或命令轻松完成此操作?Shift+T似乎允许基于模式标记消息,但不允许标记附件。

您可以标记(t
)带有附件的消息,然后通过管道(;|
)程序发送消息以提取附件。我建议您在您的.muttrc
set pipe_split = yes # sends tagged messages 1by1 otherwise they're concatenated with $pipe_sep
unset pipe_decode # don't strip headers and eval mimes when piping
我写了一个非常原始的(WIP 尚未完成但可以工作...)ruby 脚本来提取附件。你可以用它来激发自己的灵感...
#!/usr/bin/env ruby
#
# scriptname : ~/bin/mutt_utils.rb
#
# Messages tagged
# To work with tagged message you have to :set pipe_split
# Otherwise only first message tagged will be processed.

require 'optparse'
require 'fileutils'
require 'mail'

别忘了chmod +x ~/bin/mutt_utils.rb
。
使用示例:用附件标记一些消息,;
然后点击|
。
在提示符下输入~/bin/mutt_utils.rb -o ~/Desktop/
。
您现在应该可以在桌面上找到您的附件。
