need to create 1000's of directories using shell script

Hi all,

I need to create thousands of directories in a single parent directory using shell scripting code. One problem would be to generate the unique directory name for each of the 1000 iterations to create a directory every time. ie first time the directory name needs to be subdir1 and then subdir2 for the next iteration and so on.
Could anyone please help me with the script?

Thanking you,
Prashanth

ITERATIONS=1000
for i in `seq $ITERATIONS`; do mkdir /dir/subdir$i ; done

'seq' may not work in all environments.
Here is the code.
Shell Scripting Syntax (Toggle Plain Text) 
  1. !#/bin/bash
  2. for((j=1;j<=1000;j++));do
  3. mkdir subdir_$j 2> /dev/null
  4. done

to delete again:

  1. !#/bin/bash
  2. for((j=1;j<=1000;j++));do
  3. rmdir subdir_$j  2> /dev/null
  4. done
