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

In Ubuntu mh is provided by mmh package.

mmh is:

This is the mmh mail user agent (reader/sender), a command-line based mail reader that is powerful and extensible. mmh is an excellent choice for people who receive and process a lot of mail.

Unlike most mail user agents, mmh is not a single program, rather it is a set of programs that are run from the shell. This allows the user to utilize the full power of the Unix shell in coordination with mmh.

Mmh is a modified version of the electronic mail handling system nmh. Nmh (new MH) itself was originally based on the package MH-6.8.3, and was intended to be a (mostly) compatible drop-in replacement for MH. In contrast, mmh is not intended to be a drop-in replacement for nmh, rather mmh breaks compatibility to nmh in order to modernize and simplify it.

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

sudo apt-get -y install mmh

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

You can also use apt command to install mmh.

sudo apt -y install mmh

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

sudo aptitude install mmh
