for /l
is your friend:
for /l %x in (1, 1, 100) do echo %x
Starts at 1, steps by one, and finishes at 100.
WARNING: Use %%
instead of %
, if it’s in a batch file, like:
for /l %%x in (1, 1, 100) do echo %%x
(which is one of the things I really really hate about windows scripting.)
If you have multiple commands for each iteration of the loop, do this:
for /l %x in (1, 1, 100) do (
echo %x
copy %x.txt z:\whatever\etc
)
or in a batch file
for /l %%x in (1, 1, 100) do (
echo %%x
copy %%x.txt z:\whatever\etc
)
Key:
/l
denotes that the for
command will operate in a numerical fashion, rather than operating on a set of files
%x
is the loops variable
(starting value, increment of value, end condition[inclusive] )
