Parameters

filespec

   Specifies an optional file containing message text to be sent to
   the specified users. If you omit the file type, the default file
   type is TXT. The recipient-name parameter is required with the
   filespec parameter.

   If you omit the filespec parameter, MAIL is invoked to process
   MAIL commands interactively.

   No wild card characters are allowed in the file specification.


recipient-name

   Specifies one or more users to receive the message. If the
   filespec parameter is specified, this parameter is required. A
   recipient-name is the name that the user uses to log in. If any
   user is on a remote node, you should precede that recipient-name
   parameter with the name of the remote node followed by two colons
   (::).

   As an alternative to listing the user names, you can specify a
   distribution list file containing user names. Simply precede
   the distribution list file specification with an at sign (@)
   and enclose this construction in quotation marks ("). The file
   you specify should contain the user names, entered one per line,
   denoting any remote nodes as described above. If you omit the
   file type, the default file type is DIS. No wild card characters
   are allowed in the distribution list file specification.
