To reach autumn beauty

To reach autumn beauty, originally uploaded by miromir.

We have had to pass this little stream because of autumn beauty waiting for un on the other side.

It was not that hard after all but I was not very happy when I was asked to do it.

So when we passed we had to climb the hill to reach the meadows on the next shots.

For in KSH

I needed to create some files. I wanted to use seq command but not found on AIX. I had to simulate it with while. Here it is:


#!/bin/ksh
integer i=1
while ((i<5000))
do
# print "$i"
touch $i
i=i+1
done
