Better way to create a folder for each month, with another folder inside of each
 

I was going to do this manually, but figure it might be a good question to ask, as i'm sure there is a much slicker way to do it.

What I want to do is inside my directory /2012 I want to make a folder for each month of the year, like 01-2012, 02-2012, etc. then inside each ##-2012 folder, I want to make a folder named processed.

Last year I manually did mkdir's for each one, but is there some way to better create these?

probably you mean such a oneliner?

Wow, that worked great, except that it didn't do 01, 02; it did just 1, 2, etc. Is there a way to make it do the leading zero for even the single digit months?

Which shell are you using? here I have (with Bash 4.2.37)did you really type {01..12} for the sequence?

bash 3, its an older box.

I copied and pasted what you typed, so I had the 01

Thanks druuna, I did a for i in 0{1..9} and a for i in {10..12} and that did it. I wasn't sure how to combine them.
Thanks to you too Markus.

It can be done in one for loop:

Ah cool, thanks. I wasn't sure how to combine them. Wasn't sure if you should do a 10..12 or like how you did it.

In bash 4.2 you can forgo the for loop and just use:

And just to show that there is always another way to do everything in UNIX ;)
... which will avoid any shell inconsistencies and also involve less process setup/teardown than a for loop (though that really won't be noticeable for just 12 entries).
