Name
       msh - MH shell

Syntax
       msh [ -help ] [ -prompt string ] [ file ]

Description
       The command is an interactive program that implements a subset of the normal MH commands operating on a single file in format.  That is, is
       used to read a file that contains a number of messages, as opposed to the standard MH style of reading a number of files, each file being a
       separate message in a folder.

       The chief advantage of is that, unlike the normal MH style, it allows a file to have more than one message in it.  In addition, can be used
       on other files, such as message archives which have been packed using

       When invoked, reads the named file, and enters a command loop.  You can type most of the normal MH commands.  The syntax and  semantics	of
       these  commands	typed to are identical to their MH counterparts.  In cases where the nature of would be inconsistent with the way MH works
       (for example, specifying a +folder with some commands), will duly inform you.  The commands that currently supports are:
       ali	burst	 comp	 dist	  folder
       forw	inc	 mark	 mhmail   msgchk
       next	packf	 pick	 prev	  refile
       repl	rmm	 scan	 send	  show
       sortm	whatnow  whom

       In addition, has a command which gives a brief overview of all the options.  To terminate either type <CTRL/D>, or use the command.  If the
       file is writable and has been modified, then using will ask you if the file should be updated.

       A redirection facility is supported by Commands may be followed by one of the following standard ULTRIX symbols:

       |	 Open an interprocess channel; connect output to another ULTRIX command.

       >	 Write output to file.

       >>	 Append output to file.

       If file starts with a tilde (~), then a C-shell-like expansion takes place.  Note that commands are interpreted by

       When  parsing  commands	to the left of any redirection symbol, will honor the backslash () as the quote next-character symbol, and double
       quotes (") as quote-word delimiters.  All other input tokens are separated by white space (spaces and tabs).

       You may wish to use an alternative profile for the commands that executes; see for details of the $MH environment variable.

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

       -prompt string
		 Sets the prompt for If the string you specify includes white space, you must enclose it in double quotes  (").   If  you  do  not
		 specify this option, the default prompt is (msh).

       The following defaults are used by

	      file defaults to
	      -prompt (msh)

Restrictions
       The  shell  is  not the C-shell, and a lot of the facilities provided by the latter are not present in the former.  In particular, does not
       support back-quoting, history substitutions, variable substitutions, or alias substitutions.

       does not understand back-quoting.  The only effective way to use inside is to always use the -seq select option.  If you add the  following
       line to your will work equally well from both the shell and
       pick: -seq select -list

       There is a strict limit of messages per file in format which can handle.  Usually, this limit is 1000 messages.
