Editing MH Message Handling System (section)

{{Short description|E-mail client}}
The '''MH Message Handling System''' is a [[Free software|free]], [[Open-source license|open source]] [[e-mail client]].  It is different from almost all other mail reading systems in that, instead of a single program, it is made from several different programs which are designed to work from the command line provided by the [[Unix shell|shell]] on [[Unix-like]] [[operating system]]s.<ref>{{Cite web|url=http://rand-mh.sourceforge.net/book/overall/howwor.html|title = How UNIX Email Works: MH & NMH: Email for Users & Programmers}}</ref>  Another difference is that rather than storing multiple messages in a single file, messages each have their own separate file in a special directory.  Taken together, these design choices mean that it is very easy and natural to script actions on mail messages using the normal [[shell script]]ing tools. 

Descendants of MH continue to be developed under the names of '''nmh''' and '''mmh'''. GNU Mailutils also contains an implementation of MH.<ref>{{Cite web|url=https://mailutils.org/manual/html_section/mh.html|title = GNU Mailutils Manual}}</ref>
