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

dlae2.f

dlae2.f(3)							      LAPACK								dlae2.f(3)

NAME

       dlae2.f -

SYNOPSIS

   Functions/Subroutines
       subroutine dlae2 (A, B, C, RT1, RT2)
	   DLAE2

Function/Subroutine Documentation
   subroutine dlae2 (double precisionA, double precisionB, double precisionC, double precisionRT1, double precisionRT2)
       DLAE2

       Purpose:

	    DLAE2  computes the eigenvalues of a 2-by-2 symmetric matrix
	       [  A   B  ]
	       [  B   C  ].
	    On return, RT1 is the eigenvalue of larger absolute value, and RT2
	    is the eigenvalue of smaller absolute value.

       Parameters:
	   A

		     A is DOUBLE PRECISION
		     The (1,1) element of the 2-by-2 matrix.

	   B

		     B is DOUBLE PRECISION
		     The (1,2) and (2,1) elements of the 2-by-2 matrix.

	   C

		     C is DOUBLE PRECISION
		     The (2,2) element of the 2-by-2 matrix.

	   RT1

		     RT1 is DOUBLE PRECISION
		     The eigenvalue of larger absolute value.

	   RT2

		     RT2 is DOUBLE PRECISION
		     The eigenvalue of smaller absolute value.

       Further Details:

	     RT1 is accurate to a few ulps barring over/underflow.

	     RT2 may be inaccurate if there is massive cancellation in the
	     determinant A*C-B*B; higher precision or correctly rounded or
	     correctly truncated arithmetic would be needed to compute RT2
	     accurately in all cases.

	     Overflow is possible only if RT1 is within a factor of 5 of overflow.
	     Underflow is harmless if the input data is 0 or exceeds
		underflow_threshold / macheps.
