Actually it's just that the final line branches to
delbin.bat rather than CALLing delbin.bat. I hadn't
really intended the batch to be used seriously but if
you do want to use it, change the final line to:

for %%a in (CALL DEL) do %%a delbin.bat

Be wary. The CD command is necessary depending on where the
batch file is located and how it is run as the recent posts
on install.bat discuss. If you incorporated the code into
you backup batch, it would probably be using a different
current directory. The CD command can be eliminated but
there is a likelihood that the LMOD line will then exceed
128 chars because the full path needs to be quoted twice
in that line (in DIR and DEL). Alternately, since the UPDATES
directory has no sub-directories (at least in my installation)
you can use DIR /b/s.. to get the full path in %%a and keep
the line to less than 128 characters.

The echo off line is just a convenient way to initialise
delbin.bat. It is necessary to either delete that file or
clear its previous contents before appending the new DEL
commands. The FOR command above deletes delbin.bat so this
would make the "echo @echo off .." line unnecessary but a
bit safer in case of an incomplete cleanup.

The revised 2 line command would be:

dir "c:\Program Files\Grisoft\AVG6\Update\*.bin" /a-d/o-
d/b/s|lmod /L2-* del "[]" >> delbin.bat
for %%a in (CALL DEL) do %%a delbin.bat

Is there really any need to keep any of these .BIN files? I
haven't tested it but my understanding is that the .BIN files
are only used when AVG is being updated. Thereafter, they
don't get used. I think you could delete the lot without
any ill effects.

A 1 line DEL command - the shortest of all.
