To change all small number of files in a directory recusively, use "chgrp -R". To update lots of files, especially on the Lustre filesystems, you should use "lfs find" instead:

blogin4:~ $ lfs find somedirectory | xargs chgrp prj00012 blogin4:~ $ ls -ld somedirectory drwx------ 1 myaccount prj00012 4096 Jul 3 2020 somedirectory |
If your file or directory names contain spaces, you will need to use "lfs find -0 ... | xargs -0 ..." instead.
