msgchk

msgchk(1mh)															       msgchk(1mh)

Name
       msgchk - check for messages

Syntax
       msgchk [ -help ] [ -nodate ] [ -notify all|mail|nomail ] [ users ...  ]

Description
       The  program checks all known mail drops for mail that is waiting for you.  It displays whether you have mail waiting to be read or not and
       shows the date that you last read your mail.

       You can check other user's maildrops by specifying their user names as the users argument on the command line.

Options
       -help	 Prints a list of the valid options for this command.

       -date
       -nodate	 Prints the date when you last read your mail.	This is the default behavior of The -nodate option can be used of you do not  want
		 to print this date.

       -notify
       -nonotify Indicates  under  what circumstances should produce a message.  There are three legal values: all, mail, and nomail.  The default
		 is -notify all, which reports the status of the maildrop regardless of whether it has mail in it or not.  The -notify mail option
		 reports  the  status of the maildrop only if there is mail waiting.  The -notify nomail option reports the status of the maildrop
		 only if there is no mail in it.

       -source file
		 Specifies the source which are checked for mail.  The only value allowed is file, which is the user's maildrop.  Additional  val-
		 ues are supported only for use with other mail systems.

Restrictions
       does  not  understand the $MAILDROP environmental variable.  If mail is fetched from a location other than will not be able to determine if
       new mail has arrived.  However, can still be used to fetch mail when it arrives.

       For this version, the -source option only supports the value file.  Additional values are supported for use only with other mail systems.

Examples
       This example shows a user Smith checking his own maildrop:
       % msgchk
       Smith:
	  New file source mail waiting ; last read on Tue, 07 Jun 88 17
       :21:49 WET

       The next example shows a user checking the maildrops of two other local users on the same system, Rabb and Jones:
       % msgchk Rabb Jones
       Rabb:
	  No file-source mail waiting ; last read on Tue, 07 Jun 13:22:
       25 WET
       Jones:
	  New file source mail waiting ; last read on Tue, 07 Jun 17:30
       :05 WET
