Name
       show - show (list) messages

Syntax
       show [ +folder ] [ msgs ] [ -draft ] [ -[no]header ] [ -help ] [ -showproc program ] [ -noshowproc ] [ options to ]

Description
       Use  to	display  the  contents of the current message.	You can specify alternative messages or folders by using the +folder or msgs argu-
       ments.

       If a folder is given, it becomes the current folder.  The last message shown becomes the current message.

       You can specify a number of messages or a range of messages using the msgs argument.  If you specify more than one message, prompts  for  a
       <RETURN> prior to listing each message.

       Typically,  the	messages  are  listed exactly as they are, with no reformatting.  A program named by the showproc component in the file is
       invoked to do the listing, and any options not recognized by are passed along to that program.  The default program is

       By default, the command use the program to list each message, a page at a time.	When the end of the  page  is  reached,  it  waits  for  a
       <RETURN>  or a space.  If you press <RETURN>, prints the next line.  If you press the space bar, it prints the next screen of data.  At the
       end of the message, automatically returns you to the system prompt.  Press q to quit before the end of the message.

       If the profile entry Unseen-Sequence: is present and non-empty, then will remove each of the messages shown from the sequences named by the
       profile entry.

Options
       -draft	 Displays  the draft message, or the current message in your folder, if you have one set up.  You cannot give a msgs argument when
		 you use this option.

       -header
       -noheader Displays a one-line header before the message.  The header consists of the name of the folder and the message	number.   This	is
		 the default behavior.	It can be suppressed with the -noheader option.

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

       -showproc program [ options ]
       -noshowproc
		 Specifies an alternative program to list messages.  The default is to use the program defined by the showproc: entry in the file.
		 You can give options to the program at the command line.  These are passed directly to by

		 If the -noshowproc option is specified, is used instead of

		 The MH command can be used as a to show messages in a more uniform format.  See for more details.

		 If you are going to use the same all the time, it is advisable to specify it in your file.  See for more details.

       The defaults for this command are as follows:

	      +folder defaults to the current folder
	      msgs defaults to the current message
	      -header

Restrictions
       The -header option does not work when expands to more than one message.	If the is then this problem can be circumvented by referencing the
       messagename field in the format file.

       The  command updates your mail environment before showing the message.  Hence may mark messages as seen before you actually see them.  How-
       ever, this is generally not a problem, unless you are using the unseen messages mechanism, and you interrupt while  it  is  showing  unseen
       messages.

       If your is then uses a built-in it does not actually run the program.  Hence, if you define your own do not call it since will not run it.

       If is your (which is the default), then avoid running in the background with only its standard output piped to another process.	You should
       re-direct the diagnostic output of as well.

       For example, in the following incorrect example, will go into a input state:
       % show | print &
       For users of the correct command is:
       % show |& print &
       For users of the correct command is:
       % show 2>&1 | print &

Examples
       In the first example, displays the contents of message 36 in the current folder:
       % show 36

       In the next example, the program is used to list the current message:
       % show -showproc pr

Profile Components
       Path:		  To determine the user's Mail directory
       Unseen-Sequence:   To name sequences denoting unseen messages
       showproc:	  Program to show messages

Files
       The user profile.
