How To Fix biff: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu biff is provided by biff package.

biff is:

biff is a small program that prints a message to your terminal when new email arrives. Actually, the message is printed by the comsat daemon, and biff just enables/disables the u+x permission flag for the terminal, which comsat uses to determine whether or not to write to your terminal.

biff is mainly of historic interest, since there are much better alternatives (such as xlbiff and gbuffy) that are network-aware and do not require a daemon. Although there are no known security problems, running additional services is often considered risky.

By default, the biff service is disabled. To use biff email notification, you must enable this service by running ‘update-inetd –enable biff’ after the package is installed. You may also need to modify the configuration of your mail transport agent to enable comsat notification.

To fix this problem, we can install more using the command below.

sudo apt-get -y install biff

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install biff.

sudo apt -y install biff

Or if you have aptitude installed you can use the following command.

sudo aptitude install biff
