comp Command

AIX Version 4.3 Commands Reference, Volume 1

comp Command

Purpose

Composes a message.

Syntax

comp [ +Folder ] [ -draftfolder +Folder | -nodraftfolder Folder ] [ Message | -draftmessage Message ] [ -file File ] [ -editor Editor | -noedit ] [ -form FormFile ] [ -use | -nouse ] [ -nowhatnowproc | -whatnowproc Program ]

Description

The comp command starts an editor that assists you in creating and modifying messages. The comp command provides a header template, the /etc/mh/components file. By default, the specified editor creates a UserMhDirectory/draft file. If a draft file already exists, the comp command prompts you for permission to replace or use the existing file. To edit an existing draft file without being prompted for permission, specify the -use flag.

Once started, the editor prompts you to enter values for each of the message header fields. The comp command uses the definitions in the UserMhDirectory/components file for the header fields. If the file does not exist, the /etc/mh/components file is used. You can use the -form or +Folder flag to specify an alternative header format.

To exit the editor, use the Ctrl-D sequence. When you exit the editor, the comp command responds with a What now? prompt. From this prompt, you can specify any of the whatnow subcommands. To see a list of the available subcommands, press Enter. You can use the subcommands to continue composing the message, direct the disposition of the message, or end the processing of the comp command.

Note: A line of dashes or a blank line must be left between the header and the body of the message for the message to be identified when it is sent.

The -file, -draftfolder, and -draftmessage flags are used to specify existing draft messages. If the -draftfolder +Folder flag is followed by a Message parameter, it is the same as specifying the -draftmessage flag. If you wish, you can define a default Draft-Folder: entry in your Message Handler (MH) $HOME/.mh_profile file.

Flags

-draftfolder +Folder	Identifies the folder containing the draft message. If a message is not specified with this flag, the default message is new.
-draftmessage Message	Identifies the draft message. Specifying a Message variable after the -draftfolder +Folder flag is the same as specifying the -draftmessage flag.
-editor Editor	Specifies the initial editor for composing the message. If you do not specify the -editor flag, the comp command selects the default editor specified by the `Editor:` entry in your $HOME/.mh_profile file.
-file File	Places the draft message in the specified file. If you do not specify the absolute path name for the File variable, the comp command places the file in the user's MH directory. If a file is specified, the comp command prompts you for the disposition of the draft.
+Folder Message	Uses the header information from a file in the specified folder. If you specify a folder but no message, the comp command uses the current message as the default.
-form FormFile	Uses the header fields specified by the FormFile variable. The comp command treats each line in FormFile as a format string.
-help	Lists the command syntax, available switches (toggles), and version information. Note: For MH, the name of this flag must be fully spelled out.
Message	Specifies a message. Use the following references to specify a message: Number Number of the message. cur or . (period) Current message. This is the default. first First message in a folder. last Last message in a folder. next Message following the current message. prev Message preceding the current message.
-nodraftfolder	Places the draft in the UserMhDirectory/draft file. This is the default.
-noedit	Suppresses the initial edit. When you specify this flag, you receive the `What now?` prompt.
-nouse	Creates a new message.
-nowhatnowproc	Prevents interaction with the editor and the `What now?` prompt.
-use	Continues composing an existing draft of a message.
-whatnowproc Program	Starts the specified program to guide you through the composing tasks. If you specify the whatnow command as the value for the Program variable, the comp command starts an internal whatnow procedure, instead of a program with the file name whatnow.

Profile Entries

The following entries are entered in the UserMhDirectory/.mh_profile file:

`Draft-Folder:`	Sets the default folder for drafts.
`Editor:`	Sets the default initial editor.
`fileproc:`	Specifies the program used to refile messages.
`Msg-Protect:`	Sets the protection level for the new message files.
`Path:`	Specifies a user's MH directory.
`whatnowproc:`	Specifies the program used to prompt `What now?` questions.

Examples

To compose a new message, enter:
```
comp
```
The system prompts you to enter the information for the message fields. To bypass a field, press the Enter key. When the header information is complete, enter the text for the body of the message.
To finish composing a message and exit the editor, press the Ctrl-D sequence. The following prompt is displayed on your screen:
```
What now?
```
Pressing the Enter key displays a list of the whatnow subcommands. If you want to send the message, enter the send subcommand after the What now? prompt.
To compose a new message using the vi editor, enter:
```
comp -editor vi
```
To compose a message using message 8 in the schedules folder, enter:
```
comp +schedules 8 -use
```
To compose a message using a message draft in the /home/mike/parts file, enter:
```
comp -file /home/mike/parts
```
The system prompts you for the disposition of the file. Press the Enter key for a list of options. Select the appropriate option.

UserMhDirectory/components	Specifies the user's default message format. (If it exists, it overrides the system default message format.)
UserMhDirectory/draft	Contains the current draft message.
$HOME/.mh_profile	Specifies the user's MH profile.
/etc/mh/components	Identifies the system default message format.
