How to skip files in a fileset?

[dumbenis]

I know that I can skip lines at the beginning of a FILE before parsing the remainder of the FILE with:

FOR /F "skip=1000" %i IN (fileset.txt) ...

The fileset.txt FILE contains a list of filenames, created earlier with a DO- or FOR-loop.

Instead of using a FILE, can skipping files be done directly within a FILESET?

DO i IN /S *.* ...

or

FOR /R %i IN (*.*) ...

Look at Exclusion ranges. For example,

for /[!*.btm *.bat] %x in (*.*) ...

Dear Vince,

Thanks for the advice, but I can't shorten the fileset with an exclusion range.

Why not? [I don't think I understand what you want to do.]

You just want to skip the first 1000 matches?

set n=0
do file in /s *
    set n=%@inc[%n]
    if n le 1000 iterate

    rem Do stuff ...
enddo

enddo

Or even :-)

do file in /s *
    if %_do_loop le 1000 iterate
    rem Do stuff
enddo

You can build any test into the body of DO or FOR ... with wildcards or regexes

do f in *
    if %@wild[%f,*.bat] == 1 iterate
    if %@regex[.*\.bat,%f] == 1 iterate
    rem Do stuff
enddo

I'm pretty sure you cannot use the fileset to exclude anything.

Dear Vince and Charles,

Yes, the special DO keyword ITERATE with a counter is the solution. I never thought about that.

Thank you very much.
