chgrp: Change the owner group of a file/directory to match a reference file.
$ chgrp --reference=${path-to-reference_file} ${filename_or_directory}
try on your machine
The command "chgrp" is used in Linux/Unix systems to change the group ownership of a file or directory.
The "--reference" option in the command compares the group ownership of a reference file (specified by the ${path-to-reference_file}) with a target file or directory (specified by the ${filename_or_directory}). It retrieves the group ownership of the reference file and then applies it to the target file or directory.
So, when you execute the command "chgrp --reference=${path-to-reference_file} ${filename_or_directory}", it will change the group ownership of ${filename_or_directory} to the same group as the reference file specified by ${path-to-reference_file}.
