generate text sequence in powershell

Question

I just had to produce a long xml sequence for some testing purpose, a lot of elements like <hour>2009.10.30.00</hour>.

This made me drop into a linux shell and just run

for day in $(seq -w 1 30) ; do  
  for hour in $(seq -w 0 23) ; 
    do echo "<hour>2009.10.$day.$hour</hour>" ; 
  done ; 
done >out

How would I do the same in powershell on windows ?

Answer 1

Pretty similar...

$(foreach ($day in 1..30) {
    foreach ($hour in 0..23) {
        "<hour>2009.10.$day.$hour</hour>"
    }
}) > tmp.txt

Added file redirection. If you are familiar with bash the syntax should be pretty intuitive.
