- XCOPY Release 1
-
- David Scott
-
- Introduction
-
- XCOPY is a utility program which provides backup facilities for
- Archimedes ADFS file structures. It may be used to provide either a full
- back up of a particular directory or hierarchy of directories or a
- selective back up in which only those files which have been updated
- since the last back up are copied.
-
- In the selective mode of operation the program checks the file details
- on the destination disc and only copies a file from the source if it
- differs in length, file type or date or does not exist on the
- destination disc. This means that a backup can often be completed very
- quickly since the checking only takes a fraction of the time that would
- be required to make a full copy.
-
- The program normally displays a monitor message about each operation
- although an option allows this to be turned off. It concludes with a
- message giving the amount of free space available on the destination
- disc.
-
- The release and issue numbers of the program and a short help text can
- be displayed by calling the program without any parameters.
-
- The program is written in C and is available as a machine code file for
- running on the Archimedes.
-
- Commands
-
- The operation of the program is controlled by the parameters given in
- the command line when calling the program.
-
- The syntax for the command line is:
-
- *XCOPY [<source path name>] [<destination path name>] [options]
-
- If no parameters or a faulty parameter is given then the help text is
- displayed.
-
- The default source drive and directory name is ':4.$'. If another drive
- is required then it must be specified explicitly. If the drive is
- correct but a different source directory is required then this may be
- specified without specifying the drive.
-
- The default destination drive and directory name is ':0.$'. If another
- drive is required then it must be specified explicitly. If the drive is
- correct but a different destination directory is required then this may
- be specified without specifying the drive.
-
- Options are specified by a hyphen followed by a single letter:
-
- -c Confirm with the user before each item is copied to or deleted
- from the destination.
-
- -f Full copy required. The default mode copies only files which have
- changed.
-
- -r Cancel the recursive option so that the default copying of all
- subdirectories as well as the directory specified is suppressed.
-
- -v Cancel the standard verbose option so that monitoring of all
- operations on the screen is suppressed.
