Hi. on similar lines.. i need to create thousands of empty files for testing. i usually use the above or a for i loop but this would be no good for thousands of files. Is there a while less than 10000 type loop. (keep creating files "increment filename by 1" till you reach 10000 of them) type thing.

Code:
#!/bin/ksh
i=1
while [ i -le 10000 ]; do
      touch file$i
      i=$(expr $i + 1)
done

Let's speed things up a little:
Code:
i=0
while [ i -lt 10000 ]; do
  printf "%s\n" "file$((i+=1))"
done |
xargs -n32 touch

ksh93/bash:
Code:
echo file{1..10000} | xargs -n32 touch
