I have a group called service in /etc/group that has user webserver as a member.

I am trying to write to a file in /home/service using user webserver. I have a script that confirms that user webserver has write permission to /home/service, yet when I want to write to /home/service/entries_for_processing, then I get a permission denied error, even though both /home/service, and /home/service/entries_for_processing are writable by group service.

What don't I understand about group permissions that it denies me permission to write to /home/service/entries_for_processing as a member of service group? Below are the permissions of /home/service and /home/service/entries_for_processing:

# file: home/service/entries_for_processing
# owner: service
# group: service
user::rw-
group::rw-
other::---

# file: home/service/
# owner: service
# group: service
user::rwx
group::-w-
other::---

By the way, the script I mentioned that confirms that user webserver can write to /home/service, also strangely confirms that webserver cannot write to /home/service/entries_for_processing nor to any other file I try to open or create in /home/service.

    You don't have execute permissions, so you can't traverse the directory and accesss the internal directory or any other contents. – muru Jan 30 '20 at 16:03

    Since the group does not have x permissions on the directory, it lacks permissions to access files therein. – Kusalananda Jan 30 '20 at 16:03
