xarg -I {} makes abc & def both to be "{}", and you can use the "{}" to be the pattern of grep. Exmaple: If you want to find lines in file named test.txt match the pattern abc or def. And the pattern is the output of cat pattern. You can have a try: cat pattern | xargs -I {} sh -c 'grep $1 test.txt' --{}
