msh Command

Purpose

Creates a Message Handler (MH) shell.

Syntax

msh [ File ] [ -prompt String ] [ -notopcur | -topcur ]

Description

The msh command creates an MH shell for use with messages that are packed in a file. By default, this command looks for the msgbox file in the current directory. Within the MH shell, you can use the following MH commands:

ali            burst          comp        dist
folder         forw           inc         mark
mhmail         msgchk         next        packf
pick           prev           refile      repl
rmm            scan           send        show
sortm          whatnow        whom

These commands operate with limited functionality in the MH shell. To see how a command operates in the MH shell, enter the command name followed by the -help flag. Entering help or a ? (question mark) displays a list of the MH commands you can use.

To leave the msh shell, press the Ctrl-D key sequence or enter quit.

Examples

To start an msh shell, enter:
```
msh
```
If the msgbox file exists in the current directory, the system responds with a message similar to the following:
```
Reading ./msgbox, currently at message 1 of 10
```
Then, the system prompt appears as follows:
```
(msh)
```
In this example, the current message is message 1 in the msgbox file. You can now enter a modified subset of MH commands.
To start an msh shell to manipulate the messages stored in the meetings file, enter:
```
msh meetings
```
