DELBUT V 2.1(minor fix)by J.E. Arkay 6/07/88

Deletes all but a given filespec in one directory. Useful for managing your
RAM disk.

*** TESTED, BUT NOT VERY MUCH *** *** TRY IT ON A SCRATCH DISK FIRST ***

Syntax:[d:][\path\]DELBUT2 [d:][\path\]filename.ext

It will not delete a Hidden or Read-Only file; it can delete itself.

Its use of wildcards is now just like DOS (which sucks, but won't surprise you):
DELBUT ?????.?? matches ABCDE.12 and ABCD.12 and ABC.1 but not ABCD.123

For example, on our AT clone with extended memory, we use a DOS shell that runs
faster from a RAM disk. When we start AutoCAD or copy a 1.2 Meg floppy, we use
DELBUT in a batch file to erase the RAM disk except for the DOS shell.

You can use it in a batch file where DEL *.* would give its 'Y/N' message and
require a keypress. Example to DEL D:\MY-DIR\*.*:

create a 1-byte file named X (DOS won't copy a zero-byte file)
COPY X D:\MY-DIR
DELBUT D:\MY-DIR\X

It returns Errorlevel=1 if nothing is deleted or an error occurs.

For instructions, TYPE or edit the .COM file or run it with no command line.
