How do you loop in a Windows batch file?

What is the syntax for a FOR loop in a Windows batch file?

Solution 1:

If you want to do something x times, you can do this:

Example (x = 200):

FOR /L %%A IN (1,1,200) DO (
  ECHO %%A
)

1,1,200 means:

• Start = 1
• Increment per step = 1
• End = 200

Solution 2:

FOR %%A IN (list) DO command parameters

list is a list of any elements, separated by either spaces, commas or semicolons.

command can be any internal or external command, batch file or even - in OS/2 and NT - a list of commands

parameters contains the command line parameters for command. In this example, command will be executed once for every element in list, using parameters if specified.

A special type of parameter (or even command) is %%A, which will be substituted by each element from list consecutively.
