Change the “From:” address in Unix “mail”

Question

Sending a message from the Unix command line using mail TO_ADDR results in an email from $USER@$HOSTNAME. Is there a way to change the \"From:\" ad

Answer 1

Thanks BEAU

mail -s "Subject" user@address.com -- -f from@address.com

I just found this and it works for me. The man pages for mail 8.1 on CentOS 5 doesn't mention this. For -f option, the man page says:

-f Read messages from the file named by the file operand instead of the system mailbox. (See also folder.) If no file operand is specified, read messages from mbox instead of the system mailbox.

So anyway this is great to find, thanks.
