ALLBUT is a utility to delete all files EXCEPT those matching
a 'mask' or list of masks, determined by the user.
USE THIS PROGRAM WITH EXTREME CAUTION, PLEASE !
Typing 'ALLBUT' on the command line will bring up a
short information screen.
Note the wildcards follow the patterning of DOS wildcards. For
example, DEL *nt*.* will delete everything in a DOS directory,
so, conversely everything will be retained if ALLBUT *nt*.* is
used. BEWARE: ALLBUT .* will delete *EVERYTHING*, just as
DIR .* displays everything.
Parameters that will be accepted on the command line include:
A drive/path specifier, (must be first parameter) e.g.,
'ab a:' or 'ab c:\mydir'
ALLBUT will change directory to the specified path before
working its misery on the files therein. (The two examples
above would do nothing more than change the directory.) It will
then change back to the original directory.
Up to nine masks will be accepted on the command line, for
'ab *.pas *.exe *.com' will delete ALL files in the current
directory EXCEPT those with a .PAS, .EXE or .COM
'ab a: *.exe autoexec.bat' will delete ALL files on drive A's
current directory, EXCEPT those with a .EXE
extension or a name of 'AUTOEXEC.BAT'.
'ab c:\mydir *.com' will delete ALL files in the
subdirectory MYDIR on drive C,
EXCEPT those with a .COM extension.
FIVE switches are currently allowed. Those are /C, /D, /H, /I, /V
'/C' allows you to change the internal masks and clone a
new copy of ALLBUT with the new masks.
'/D' displays the list of internal filemasks.
'/H' or no command line parameters causes a help screen
to be displayed.
'/V' issues a verification prompt for each file matching the
'/I' turns on the internal filemasks for a single
invocation of ALLBUT.
So, a command line entry of "AB /I" will delete ALL files in
the target directory EXCEPT those matching one or more of the
ALLBUT *might* strike some as unnecessary but I have had many
occasions where I needed it. Perhaps you have had the same
experience. It basically operates as an inverse of the DOS
'delete' command line parameters.
The command line can be used to augment the internal masks if so
desired. Just type /I and your other masks on the command line.
Either may be first.
Although the source uses Turbo Power's TPCRT unit, the changes to
remove dependence on that are fairly simple and not too penalizing.
I can and will include the TPClone unit that Turbo Power provided
as part of the 'BONUS' package and graciously has consented to
allow users to distribute. The FASTWRITE functions are all I'm
using from Turbo Power in ALLBUT, aside from the FASTWRITE.
I can be found on GENIE as 'WILLSCOTT'.
