I want to set the group permissions for all files and subdirectories within a certain parent directory to whatever the user permission setting for that specific file or directory is.For example, everything under /path/to/parentdir# Permissions before# Path                      Permissions/path/to/parentdir/file1    755/path/to/parentdir/file2    644/path/to/parentdir/file3    600# Permissions after/path/to/parentdir/file1    775/path/to/parentdir/file2    664/path/to/parentdir/file3    660I'm hoping there's a simple way to do this in hopefully one command. I can think of ways using a script with a bunch of commands, but it feels like there should be a pretty direct way of doing it.Thanks in advance!
Make group permissions same as user permissions
permissions;chmod
This is what you want:chmod -R g=u directory
