I have a 100 node CentOS 7.5 HPC cluster and I want to give everyone permission to run a script owned by root on all nodes, /usr/sbin/dropcaches.sh Logging into all 100 nodes and doing visudo would be extremely painful and prone to mistakes. Is it possible to create a file in /etc/sudoers.d on the head node and just cp it to every node in the cluster that gives everyone permission to execute /usr/sbin/dropcaches.sh please? Many thanks M
