from: Print the mail from the specified address.
$ from --sender=${me@example-com}
try on your machine
This command is using the "from" directive to specify the sender of a message or email.
The part "--sender=${me@example-com}" suggests that the sender's address should be set to "me@example-com".
The "${me@example-com}" syntax indicates that a variable named "me@example-com" is being used to set the sender. So, before running this command, you would need to define this variable with the appropriate email address.
