how to attach attachment to mail and download it

how can attachment sends through mail command in linux with mail command either w开发者_Python百科ith mail -s or -v option also how please confirm how to download the attachments from it . and how one should knows with mail command that attachment is present with the particular mail

Your questions are not very clear.

I don't think the "mail" command can attach files to an e-mail. There are other commands that can do it, though. e.g. the mutt command can do it.

mutt -s "This is the subject" -a /path/to/file recipient@example.com

For extracting the attachments from a message, again something like mutt or pine would probably be better.

What exactly are you trying to do? Read and send mail interactively from the command line? From a script?

depends on which version of mail are you using. In later linux release, mail actually refers to mailx, which you can use the -a option directly
