Synopsis

Use this command to repeat a specified command any number of times. You specify an arbitrary variable name and a set of values to be iterated through. For each value in the set, the command is repeated. The options used by for are the following:

for /r [path] %variable in (set) do command [arguments]
for /l %variable in (start,step,end) do command
