Yes, 11,14, and 17 would then go to the first file again.

I am trying to use KSH to complete this task. Below is what I have so far, but the count variable does not appear to be resetting to 1 after it reaches 11. Also, I am getting output similar to:

File_split_DC.sh[42]: 2: not found.
File_split_DC.sh[42]: 3: not found.
File_split_DC.sh[42]: 4: not found.

The name of my script is "File_split_DC.sh"

#!/usr/bin/ksh

count=1

while read line
do

case $count in
1)
echo "$line" >> RT1.txt
;;
2)
echo "$line" >> RT2.txt
;;
3)
echo "$line" >> RT3.txt
;;
4)
echo "$line" >> RT1.txt
;;
5)
echo "$line" >> RT2.txt
;;
6)
echo "$line" >> RT3.txt
;;
7)
echo "$line" >> RT1.txt
;;
8)
echo "$line" >> RT2.txt
;;
9)
echo "$line" >> RT3.txt
;;
10)
echo "$line" >> RT4.txt
;;
esac
(( count+=1 ))

if $count -gt 10; then
count=1

fi
done < My_Test.txt

exit 0
