You can ftp it from oak.oakland.edu:/SimTel/msdos/4dos/rmd200.zip

Really simple:
alias deldir=`set DELETEDIR=%_CWDS^cd ..^del %DELETEDIR /szxqy^unset DELETEDIR`

I do not like these commands (an error and you have lost your data!). So take
your time and write a good batch file that also does some checking before it
deletes the directory!

Greetings,

alias zap='set dir=%_cwd ^ cd .. ^ del /sxyz %dir ^ unset dir'

You have to start in the parent dir, but you simply type
      NUKE DIRNAME
and it will remove _ANYTHING_ in that directory (including subdirs), and the
dir itself.

The alias is:

      NUKE   DEL /S /Z /Q /X /Y

This requires DOS 6.00 minimum and 4DOS 4.00 minimum.

Watch out!  This command requires no user input and can easily erase
everything on your hard disk if you type NUKE \  !

alias nuke DEL /Q/S/Y/X/Z %&

/q=quiet mode
/s=act on subdirectories too
/y=assume yes response to everything
/x=remove empty subdirectories
/z=zap all files regardless of their attributes

eg.
NUKE dirname  (wipes-out entire directory structure of dirname and below)

This is a very powerful and potentially dangerous command.  You must be
absolutely sure that you wish to wipe out the directory and all its sub's.
I have only once made the mistake of wiping out an entire directory
structure that I did not intend to.  I was on the wrong drive when I
typed the command, and unfortunately that drive just happened to have
a directory with the same name as the drive that I had intended to nuke.
Also, when you delete a directory structure using this method, it is
very difficult to recover the files, even with Norton Utilities.  If you
have a deletion tracker program running, then it gets easier.  Anyway,
I have found the command to be very useful.

There are several safeguards in that program. It will warn you, for instance,
if you try to delete a root directory, or a directory that's higher than
the current directory. There's also an environment variable NO_RMD in which
you can specify directories that should never be deleted.

...isdir %d then^del %d/sxyz^else^echo %d isn't a directory!^ve^endiff^...
...popd>&nul)

Connect at the dots and remove them; note that 've' is an alias for an
error-announcement! It'll probably give an error on your system, but you can
just delete it without losing much :-)

Works for me, and I run MS-DOS 5.0. Don't know why your NUKE needs 6.00.
Perhaps you are confused with DELTREE (I think) which is in DOS 6.x?

I have an alias rdq which uses the q switch too, but I usually want to see
what garbage I'm deleting. And if something does go wrong you could break the
del command which saves a lot of undeleting.

        alias deltree=`iff %&.==. then^select /ad del /sqxz (.)^else^
                        del /sqxz %&^endiff`

        Then, if you simply type "deltree" with no arguments, it shows
        you a screen with all the available subdirs to delete, and if
        the alias is called with arguments, as in "deltree subdir1 subdir2
        subdir3 ... subdirn", it prompts if you really want to delete these
        subdirs, and if your response is "Y", *POUF* they're gone.

   The del [subdirectory] /yqszx command is great and works well,
but don't try to do this selectively using the except command - it
can do some unexpected things.  I forgot that 'except' normally works
on files only, and from the root directory launched the following
command:

except (dos 4dos etc bin) del *.* /yqszx

This was supposed to clear out the entire disk except for the directories
dos, 4dos, etc, and bin, but since they were directories and not files,
it didn't have the desired effect.  In fact, taking only a few seconds,
all the data on the hard disk was gone.  Luckily, I
was still connected to my network and had very recently done a full
image backup, so I only lost 20 minutes.  Without a network, or without
a recent backup, I would have been hosed.

Bottom line:  Be careful!

where did my .sig go?

4dos enhanced a lot of simple dos-commands by adding /s. Why didn't
they enhance "except"?

They found a feature in DOS (hidden files) which (only) sometimes
works well; therefor "except" works only sometimes well.

Have a look at the example in the (version 4) docs:

  except (memo*.* *.wks) del *.*

A user who believes in the power of 4dos assumes that

  except (memo*.* *.wks) del /s *.*

will do good job.

Please, please: re-implement "except" without using "hidden files".
It will use some more time, but it will be a lot safer. You may
than add an "unsafe, but quick" switch for those who like such a
behaviour.
