How do I give user sudo access to modify files in certain directories /etc/

Question

I have a user who needs to modify files in /etc/haproxy and /etc/tomcat. I tried to create a sudoers file with:

%usergroup ALL=(ALL) NOPASSWD: /etc/haproxy /etc/tomcat

But it didn't work. Any help would be greatly appreciated.

Sudoers won't give you the type of control you need. Instead, consider using groups. Assuming that those programs run as root:

1. Define a new group
2. Modify the group for those directories to be the new group.
3. Give the group read/write permission to those directories.
