Listing multiple files in windows cmd

i have multiple files like

how to do list files from new_30 to new_50

i have tried this command but it wont work

dir new*{30-50}.txt

my exact requirement is to get line count of these files

the command which work is

FOR %i IN (new*.txt) DO find %i /c /v ""

but at the place of new*.txt i want to get line count of 20 files only as said earlier

You could try something like this:

FOR %i IN (new*_3*.txt new*_4*.txt new*_5*.txt) DO find %i /c /v ""

Do you have Power Shell or Cygwin?
