ARCHIVED: What are some equivalent commands in VMS Mail and the Unix electronic mail program Berkeley mail and Elm?

This content has been archived, and is no longer maintained by Indiana University. Information here may no longer be accurate, and links may no longer be available or reliable.

Note: Elm is not available on any UITS systems.

Below is a list of some roughly equivalent commands in three different electronic mail programs. It is intended as an aid for someone who knows one of the three mail programs and wishes to learn another.

Please use this list with discretion; it is not a replacement for other mail documentation such as the online help. This list does not explain exactly what each command does, and it assumes knowledge of many aspects of VMS and Unix. Many features of each mail program have been omitted because they do not have equivalents in the others.

Notes on the non-standard notation used:

  • A semicolon separates commands and represents the Return key.
  • Items enclosed in curly brackets are not meant to be typed literally.
  • Items preceded by $ or % should be typed at the command line prompt of your account. ($ represents the VMS prompt and % represents the Unix prompt. The prompt on your account may look different if you have made changes to your account.) All other commands should be typed within the mail program (at the mail prompt).

"Berkeley Mail" refers to the mailer that is traditionally invoked by "mail" or "Mail" on most Unix systems (although many accounts have aliased "mail" to the more modern mailers Pine or Elm.)
