I'd like to ADD myself (already in the webapps group) with
drwxrwxrwx permission to the whole folder recursively:
$ ls -l /var/lib/tomcat8/webapps total 67904 drwxrwxrwx 3 root webapps 4096 Oct 1 21:39 ROOT drwxrwxrwx 8 tomcat8 tomcat8 4096 Oct 11 18:01 AppWeb -rwxrwxrwx 1 tomcat8 tomcat8 69522664 Oct 11 18:01 AppWeb.war
I don't want to remove permissions from users that already have it.
Other posts either come close to helping me or I don't understand, because I'm new.
It may help to know:
$ getent group webapps webapps:x:1002:tony,root,tomcat8
