Hi,
I have a bash loop which I have significantly sped up by using:
for ((i=0;i<=Z;i++)); do echo $i; done
Does
for ((i=0;i<=Z;i++)); do echo $i; done> $OUT
Help? It at least avoids reopening the file every time.
instead of other format for loops as well as using internal math like:
NEWX=$(($EAST+$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
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??
Cheers,
Barrett.
