Here are the steps to send the file to someone using mutt in the command line:

1. Open a terminal window.
2. Compose the email using the following command:
   • mutt -a echomy.sql -s "Subject of your email" [email protected]
3. Within the mutt interface:
   • Type your email message in the text area.
   • When finished, press Ctrl+D to send the email.
4. Replace [email protected] with the actual email address of the recipient.
5. Replace Subject of your email with your desired subject line.

Additional tips:

• To send multiple files, list them after the -a option, separated by spaces (e.g., -a file1.txt file2.pdf).
• To specify a different email address for the sender, use the -e option (e.g., -e [email protected]).
• To include a carbon copy (CC) recipient, use the -c option (e.g., -c [email protected]).
• To include a blind carbon copy (BCC) recipient, use the -b option (e.g., -b [email protected]).

Remember:

• Mutt uses your default email address configured for your system unless you specify otherwise with the -e option.
• Mutt requires a working email setup for sending emails. Ensure your system’s email configuration is correct.
