mail

The command line tool "mail" is a utility that allows users to send and receive emails from the command line interface. It is commonly available on Unix-like operating systems. Users can compose emails, specify recipients, subject, and content using the command line options. The "mail" command supports functionality such as attaching files, setting priorities, and carbon copying recipients. Emails can be sent to both external email addresses and local users on the same system. Incoming emails are stored in the user's mailbox, usually located in the /var/mail directory. Users can use the "mail" command to read, reply to, and delete messages stored in their mailbox. The tool provides a straightforward and efficient way for automated scripts and programs to send email notifications and updates. The "mail" command can be used with other command line tools like "grep" and "awk" to filter and manipulate email content. It is important to configure the appropriate mail server settings and authentication credentials for successful email sending and receiving.
