Hi,
I have a bash loop which I have significantly sped up by using:

for ((i=3D0;i<=3DZ;i++)); do echo $i; done

instead of other format for loops as well as using internal math like:

NEWX=3D$(($EAST+$DX))

Instead of let or expr. This process is now heaps faster but I want to
echo the data to a file but not have to write to a file on each loop
cycle as it slows it down.

On native linux you would write:

echo $NEWX > /dev/shm/new=20

and then at the end of all the loops at the end of the script write to a
file with:

cat /dev/shm/new > $OUT

--> Finally to the question. How do you do this with Cygwin??=20

Cheers,

Barrett.
