Convert Relative path to Absolute path, without changing directory to the file location.
Hello,

I am creating a file with all the source folders included in my git branch, when i grep for the used source, i found source included as relative path instead of absolute path, how can convert relative path to absolute path without changing directory to that folder and using readlink -f ?

Code:
grep -r "src +=" --include=*.spec $REPOROOT

src += ../src
src += ../stubs
src += ../../dataLU/src
src += ../../src   
src += ../src
src += ../export/src
src += ../src
src += ../src       
src += ../../src    
src += ../src

Code:
grep -r "src +=" --include=*.spec $REPOROOT | cut -d "=" -f2

../src
../stubs
../../dataLU/src
../../src    
../src       
../export/src
../src
../src      
../../src   
../src

i tried using the below two ways
Code:
echo "$(cd "$(dirname "../../dataLu/src")"; pwd)/$(basename "../../dataLu/src")"
readlink -f ../../dataLu/src

while this worked, i have to change directory to the location of the spec file there are more than 1000 spec files, hence i want to get the path from the top of the repo without changing directory

desired results are
Code:
a/src
b/src
x/y/dataLu/src

Thank you!

OS: linux SUSE (I don't have realpath)
Shell : bash

mlib_imageerode4

mlib_ImageErode4(3MLIB) 				    mediaLib Library Functions					   mlib_ImageErode4(3MLIB)

NAME

       mlib_ImageErode4 - four neighbor erode

SYNOPSIS

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

       mlib_status mlib_ImageErode4(mlib_image *dst, const mlib_image *src);

DESCRIPTION

       The  mlib_ImageErode4()	function  performs  an erode operation on an image by using each pixel's four orthogonal neighbors. The source and
       destination images must be single-channel images. The data type can be MLIB_BIT, MLIB_SHORT, MLIB_USHORT, or MLIB_INT.

       For 4-neighbor binary images, it uses the following equation:

	 dst[x][y][0] = AND{ src[x][y][0],
			     src[x-1][y][0], src[x+1][y][0],
			     src[x][y-1][0], src[x][y+1][0] }

       For 4-neighbor grayscale images, it uses the following equation:

	 dst[x][y][0] = MIN{ src[x][y][0],
			     src[x-1][y][0], src[x+1][y][0],
			     src[x][y-1][0], src[x][y+1][0] }

       where x = 1, ..., w-2; y = 1, ..., h-2.

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.
