Hi,

If you use gvim you can use this:
select the lines in with visual mode and run:
:'<,'>:g/.*/exe "!wc ".getline(".")
(assuming the files are in your current path, which you can check with ':pwd',
and adjust with ':cd' commands)

If you use vim (in terminal) a better solution is to use:
:'<,'>:g/.*/echo system("wc ".getline("."))

Best regards,
Marcin
