## Name

HELP — Displays the usage and syntax of OS-9 commands.OS-9 Level Two

## Synopsis

`help` {`command`}

## Description

Provide as argument the command for which you want syntax help. Include as many command names in one help line as you wish. The proper form and syntax appears for each valid command you include.

## Notes

To use help, first copy `Cmds.hp` from the `SYS` directory of the CONFIG/BOOT Diskette to the `SYS` directory of your system diskette. Next, copy help from the `CMDS` directory of the CONFIG/BOOT Diskette to the `CMDS` directory of your system diskette as follows:

Procedure for one disk drive:

1. With OS-9 booted and the system diskette in your drive, type:

    	LOAD COPY ENTER

2. Replace the system diskete with the CONFIG/BOOT Diskette and type:

    	COPY /D0/SYS/CMDS.HP /D0/SYS/CMDS.HP -S #30K ENTER

3. Exchange the two diskettes as requested by the screen prompts until the process is complete.

4. Again, place the CONFIG/BOOT Diskette in the drive, and type:

    	COPY /D0/CMDS/help /D0/CMDS/help -S #30K ENTER

5. Swap diskettes as requested until the process is complete.

Procedure for two disk drives

1. With OS-9 booted, place the CONFIG/BOOT Diskette in Drive 1. Be sure the system diskette is in Drive 0.

2. Type:

    	COPY /D1/SYS/CMDS.HP /D0/SYS/CMDS.HP ENTER

3. When the first copy is complete, type:

    	COPY /D1/CMDS/help /D0/CMDS/help ENTER

`Cmds.hp` is a data file, not a text file, and you cannot successfully display it on your screen or edit it with a standard text editor. It contains help for standard OS-9 commands.

Help displays the form and syntax of the specified command. If you use a non-standard command name, a screen display tells you that help is not available for that command.

Examples:

    	HELP BACKUP ENTER
    	BACKUP [e][s][-v][dev][dev]
    	Copies all data from one device to another

    	HELP ME ENTER
    	ME Help not available

    	HELP ENTER
    	HELP [command name][...]
