Take input from read and place it a string in another file
Hi,
This is most likely a dumb question but I could not find answer to it elsewhere.

I'm building a simple menu with case /esac and want to read user's input:

Please enter XYZ ; read XYZ

How do I take the value of XYZ and insert it as a variable $XYZ in file file.txt ?

I may need to explain that I have existing variable IP="address" in file.txt and I need to substitute address with XYZ from the user's input

mlib_ImageColorXYZ2RGB_Fp(3MLIB)			    mediaLib Library Functions				  mlib_ImageColorXYZ2RGB_Fp(3MLIB)

NAME

       mlib_ImageColorXYZ2RGB_Fp - XYZ to RGB color conversion

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageColorXYZ2RGB_Fp(mlib_image *dst, const mlib_image *src);

DESCRIPTION

       The mlib_ImageColorXYZ2RGB_Fp() function performs a color space conversion from CIE XYZ to ITU-R Rec.708 RGB with D64 white point.

       The source and destination images must be three-channel images.

       It uses the following equation:

       |R|   |cmat[0] cmat[1] cmat[2]|	 |X|
       |G| = |cmat[3] cmat[4] cmat[5]| * |Y|
       |B|   |cmat[6] cmat[7] cmat[8]|	 |Z|

       where

       cmat[] = { 3.240479, -1.537150, -0.498535,
		 -0.969256,  1.875992,	0.041566,
		  0.055648, -0.204043,	1.057311 };
       src[x][y] = { X, Y, Z };
       dst[x][y] = { R, G, B };

PARAMETERS

       The function takes the following arguments:

       dst	       Pointer to destination image.

       src	       Pointer to source image.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
