Module Name:
Argument
Abstract:
Argument processing for the Replace utility
Author:
Ramon Juan San Andres (ramonsa) 01-May-1991
Notes:
The arguments accepted by the Replace utility are:
Source path.- Source path.
Destination path.- Destination path.
Add switch.- Adds new files to the target directory instead of
replacing existing one. Cannot use with Subdir
switch or CompareTime switch.
Prompt switch.- Prompts before adding/replacing a file.
ReadOnly switch.- Replaces red-only files as well as regular files.
Subdir switch.- Recurses along the destination path.
CompareTime switch.-Replaces only thos files on the target path that
are older than the corresponding file in the
source path.
Wait switch.- Waits for the user to type any key before starting.
Help switch.- Displays usage
