Simple Script to create folders


I want to write a small script that will create folders named from `AAAA' all the way to `ZZZZ'.

That is:

Any ideas?

Example for bash
for i in {A..Z}{A..Z}{A..Z}{A..Z};do mkdir $i;done

Sorry I'm a complete novice and may have done something wrong. I tried exactly what you had written above. It only seems to create a folder title `{A..Z}{A..Z}{A..Z}{A..Z}'.

I realized it would be easier to do this with numbers (the names of the folders don't matter to me as long as they're sequential), so I wrote this:
for ((i = 0; i <= 9; i++))
  for((j = 0; j <= 9; j++))
    for((k = 0; k <= 9; k++))
      for((l = 0; l <= 9; l++))
        for((m = 1; m <= 9; m++))
          mkdir "$i$j$k$l$m" #This will create the folders

The solution from danmero works perfectly (in bash, ksh and in csh).

If you want to use numbers, this would be quicker I tbink:

printf "%04d\n" $(seq 0 9999) | xargs -I{} mkdir {}

(you should - but may not - have seq on your system!)

Why do you have five for loops? If hope you have 100,000 free inodes!

$ cat
for (AAAA..ZZZZ)  {
    mkdir $_;    

The above perl script will do, store and run it as
$ perl

Or run from your command line itself.
