This command is used to send an email using the sendmail program. Here's the breakdown of each component:

sendmail: It is a command-line program available on Unix-like systems used to send email from a command prompt or from within scripts or programs.
${username}: It is a placeholder that represents the recipient's email address. You need to replace ${username} with the actual email address.
<: This operator is used to redirect the contents of a file as input to a command. In this case, it is redirecting the contents of the file ${message-txt} as the email body.
${message-txt}: It refers to a file containing the message or body of the email that you want to send. Similar to ${username}, you need to replace ${message-txt} with the actual file name that contains the email message.

Overall, this command takes the email address (stored in ${username}) and the email message (stored in ${message-txt} file) and sends it using the sendmail program, allowing you to automate the process of sending emails.
