Let
us
go a step ahead now.
You will certainly want to
copy
several
files
at
once.
No problem at all:
You are free to specify
ambiguous
filenames both with source and destination.
So if you want to copy
all
".COM" files from A: to B:, you would type:
* A:*.COM B:
As simple is copying an entire disk:
*
A: B:
As you may specify ambiguous filenames both with source and destination,
a
curious side effect results:
the files are renamed one by
one.
For
instance,
if you should decide to attach a new file type ".OLD" to
all
11
.COM" files on the destination (for whatever reason),
the command line
looks like this:
* A:*.COM B:*.OLD
Of Course,
you can as well copy single files in such a manner that they
get new names on the destination drive, for example:
*
A:$COPY.COM B:$COPY.OLD
Again,
there is a restriction:
When you specify an ambiguous
the source file,
but an unambiguous name for the destination,
on
strike.
This would mean that all files are to receive the
on
the
destination drive,
thus leaving the file transferred
noble solitude.

To
recall
the conditions a command line must satisfy in
order
to
be
accepted by·$COPY:
- always specify two file designations
- Source and/or destination can be ambiguous
- To copy all files of a drive, the drive name suffices
- An ambiguous filename for the source together with an
unambigous
name for the destination makes no sense and is not permitted.
