Managing File Attributes and Permissions

In order to allow access to the /opt/myapp directory, the student will need to provide specific permissions to the directory itself so it can be read by users other than the owner.

Accomplish this task with:

sudo chmod 755 /opt/myapp

Optionally, although less secure, the following would meet the requirements as well:

sudo chmod 777 /opt/myapp

The student is asked to allow read and write permissions to all files and folders within the /opt/myapp directory (including files within the subfolders recursively).

This task can be completed successfully via:

sudo chmod 666 -R /opt/myapp/*

Note: For users to be able to navigate into directories, the directories must be set as executable. You can do this with:

    sudo find /opt/myapp -type d -exec chmod o+x {} \;
