[Solved] Inserting a line beginning with regex
I have been trying to insert a line after a regex but I can't do it. Here is the code I am using:

Code:
cat saved_doc 
SET type = type1 
SET type = STORE = y
/vol/san_e1
/vol/san_5
/vol/san_e9
/vol/san_e11
/vol/san_e12
/vol/san_e13
/vol/san_e14
/vol/san_e16
/vol/san_e17
/vol/san_e18
/vol/san_e19
/vol/san_e20
/vol/san_e23
/vol/san_e24
/vol/san_e26
/vol/san_e27
/vol/san_e28

What I have done is this:

Code:
cat saved_doc |gawk '{printf "NEW\n"; print}'

This makes the file look good except that I want NEW to be inserted starting after the line SET type = STORE = y only. Then the file should look like this:

Code:
SET type = type1 
SET type = STORE = y
NEW
/vol/san_e1
NEW
/vol/san_5
NEW
/vol/san_e9
NEW
/vol/san_e11
NEW
/vol/san_e12
NEW
/vol/san_e13
NEW
/vol/san_e14
NEW
/vol/san_e16
NEW
/vol/san_e17
NEW
/vol/san_e18
NEW
/vol/san_e19
NEW
/vol/san_e20
NEW
/vol/san_e23
NEW
/vol/san_e24
NEW
/vol/san_e26
NEW
/vol/san_e27

Anybody have an idea? Once I have this fixed, I can place it into the rest of the script but for now NEW starts at the first line of the file and goes to the end. I've tried sed, but that goes for specific lines and
Code:
NR %2 = 0

but that captures even lines and so on.

DESCRIPTION

       Each of these functions casts a ray (or rays) through a three-dimensional(3D) data set, then computes and returns the interpolated samples
       at each step along the way.

       In trilinear interpolation, the value at point P is computed from its eight surrounding neighbors based on the equation below.

	 P = (1-a)*(1-b)*(1-c)*P0 +
	     a*(1-b)*(1-c)*Px + (1-a)*b*(1-c)*Py + (1-a)*(1-b)*c*Pz +
	     a*b*(1-c)*Pxy + a*(1-b)*c*Pxz + (1-a)*b*c*Pyz +
	     a*b*c*Pxyz

       where a, b, and c are the fractional parts of the coordinates of point P.

       The trilinear interpolation is represented by the following figure:

       Printed copy or docs.sun.com displays a figure that represents the trilinear interpolation.

       In nearest neighbor operation, the sample value at point P is replaced by the value of the nearest neighbor voxel.

PARAMETERS

       Each of the functions takes the following arguments:

       rays	 Casting rays.

       vol	 Volume data that consists of slices.

       buffer	 Working buffer.

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
