Linux Shell sends emails with attachments

If there is no body file, use echo to directly extract the body, for example:

Echo "this is content" | mutt-s "this is subject"-A/path/Yourfile abc@local.domain-C bbb@local.domain

If there is a body file, use

CAT/path/contentfile | mutt-s "this is subject"-A/path/Yourfile abc@local.domain-C bbb@local.domain

Mutt is the next powerful mail client software in Linux.

-S is the topic

-A is an attachment.

-C is CC, and multiple CC is-C, such

CAT/path/contentfile | mutt-s "this is subject"-A/path/Yourfile abc@local.domain-C bbb@local.domain-C ccc@local.domain-C ddd@local.domain

If multiple emails are sent, you can directly list them, as shown in figure

CAT/path/contentfile | mutt-s "this is subject"-A/path/Yourfile abc@local.domain bbb@local.domain ccc@local.domain ddd@local.domain
