'-- home/

|-- alice/

| '-- Documents/

| '-- notice.md

'-- bob/

|-- report.pdf

'-- Downloads/

- bob has left the building. User alice has full control over bob's files and directories.

- User alice is in group 'manager' and user 'bob' is in group 'staff'.

- Before each question assume directory tree is as above; you are user alice in '/home/alice'.

6. Use find to list files in alice's home and sub-directories. Redirect errors to /dev/null
