msh (1) - Linux Man Pages
msh: nmh shell (and BBoard reader)
msh - nmh shell (and BBoard reader)
- msh [-prompt string] [-scan | -noscan] [-topcur | -notopcur] [file] [-version] [-help]
STATUSmsh is deprecated and will be removed from the next nmh release.
When invoked, msh reads the named file, and enters a command loop. The user may type most of the normal nmh commands. The syntax and semantics of these commands typed to msh are identical to their nmh counterparts. In cases where the nature of msh would be inconsistent (e.g., specifying a +folder with some commands), msh will duly inform the user. The commands that msh currently supports (in some slightly modified or restricted forms) are:
ali burst comp dist folder forw inc mark mhmail mhn msgchk next packf pick prev refile repl rmm scan send show sortm whatnow whom
In addition, msh has a help command which gives a brief overview. To terminate msh, type CTRL-D, or use the quit command.
If the file is writable and has been modified, then using quit will query the user if the file should be updated.
The -prompt string switch sets the prompting string for msh.
You may wish to use an alternate nmh profile for the commands that msh executes; see mh-profile(5) for details about the $MH environment variable.
The exit command is identical to the quit command in msh.
msh supports an output redirection facility. Commands may be followed by one of
^> file~^write output to file ^>> file~^append output to file ^| command~^pipe output to UNIX command
If file starts with a ``~'' (tilde), then a csh-like expansion takes place. Note that command is interpreted by sh. Also note that msh does NOT support history substitutions, variable substitutions, or alias substitutions.
When parsing commands to the left of any redirection symbol, msh will honor `\' (backslash) as the quote next-character symbol, and ```' (double-quote) as quote-word delimiters. All other input tokens are separated by whitespace (spaces and tabs).

`file' defaults to ``./msgbox'' `-prompt
(msh)`-noscan' `-notopcur' '
There is a strict limit of messages per file in packf'd format which msh can handle. Usually, this limit is 1000 messages.
Please remember that msh is not the C-Shell, and that a lot of the nice facilities provided by the latter are not present in the former.
In particular, msh does not understand backquoting, so the only effective way to use pick inside msh is to always use the -seq select switch. Clever users of nmh will put the line
- pick: -seq select -list
in their .mh_profile file so that pick works equally well from both the shell and msh.
sortm always uses -noverbose and if -textfield field is used, -limit 0.
The msh program inherits most (if not all) of the bugs from the nmh commands it implements.
