UNIX for Beginners Questions & Answers

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!
