SUMMARY
This article describes the command-line switches you can use when you run the MS-DOS version (Scanreg.exe) or the Windows version (Scanregw.exe) of the Registry Checker tool.



Syntax
MS-DOS Version:

Scanreg.exe [/backup] [/restore] ["/comment=< >"] [/fix]

Scanreg.exe [backup] [/restore] ["/comment=< >"] [/fix] [/opt]

Windows Version:

Scanregw.exe [/backup] ["/comment=< >"] [/autoscan] [/scanonly] [filename]

Description of Switches
The following table lists each command-line switch and its description:

  Switch              Description --  /backup             Backs up the registry and related files without displaying any prompts.

/restore           Displays a list of available backup files, sorted by the date and time the backup was created.

"/comment= "  Enables you to add a descriptive comment to the registry backup.

/fix               Repairs any damaged portions of the registry, and optimizes it by rebuilding it without unused space.

/autoscan          Automatically scans the registry and backs it up                       without displaying any prompts if there is no                       backup for that date.

/scanonly          Scans the registry and displays a message if any errors are found. This switch does not back up the registry.

filename           Scans the registry file specified and displays a                       message indicating whether or not any errors were found. This switch does not back up the registry.

/opt               The /opt command-line switch causes the Registry Checker tool to optimize the registry by removing unused space.

The Registry Scan Results dialog box appears only when you use the Scanregw.exe command without any command-line switches. If no registry errors are found when you run Scanregw.exe, you are prompted to create a backup copy of your current registry.

The "/comment= " switch can be used by itself or with the /backup switch. For example, you can type either of the following lines at a command prompt:

scanreg.exe "/comment=this is a registry backup"

scanreg.exe /backup "/comment=this is a registry backup"

The first command line starts the Registry Checker tool graphical user interface (GUI) and prompts you to create a registry backup. The second command line creates a backup copy of your registry and adds your comment without starting the Registry Checker tool GUI.
