Understanding the for Loop

[ Thanks to Andrew

for this link. ]

“The for loop starts with ‘for’ and is followed by a variable,
in the example below ‘i’. The for loop is designed to be used with
a list of items to work through, like files, numbers, folders, etc.
This list must be supplied in some form. The ‘do’ is followed by
the method of manipulation, what you want to do with the
information that you are working through. In the example the ‘do’
is simply to send to screen each of the numbers. Close the for loop
with the ‘done’.”
