[solved] How do i extract Linux command out of an e-mail file?

Hello,

please how can i extract an Linux command out of e-mail message?

I sent an e-mail with this text:

and in the received e-mail file is:

The e-mail encoding is:
Content-Type: multipart/alternative
Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: quoted-printable

Please which example command can i use to extract that Linux command out of the mail file not knowing which command the file will contain, only knowing that the command will be after string "cmd: " ?

I am able to extract alphanumeric string, but i do not know how to do what i explained.

Thank You

 

I think this would be quite difficult awk or sed command/s, so i think i will rather make sure e-mail is sent without any special html formating (as a plain text), that way the command seems to remain same as it was typed.
