sed example:

an example file: img.h
#ifndef _GAN_IMAGE_RGBA_UINT_H
#define _GAN_IMAGE_RGBA_UINT_H
#include
#include

task: replace with "image_colour_noc.h"

done with:
sed -e 's//"\1"/g' img.h

sed example: bash

for i in *.c; do sed -e 's//"..\/common\/\1"/g' -e 's//"..\/linalg\/\1"/g' -e 's//"\1"/g' $i > sedtest/$i; done

sed example:
