OSCP Linux Practice Exam

To delete a file, what permissions do you need?

Write and execute for the file Read and write for the directory Write and execute for the directory Execute and read for the directory

Correct Answer:

Write and execute for the directory

Explanation:

Deleting a file is a change to the directory’s contents, not a change to the file itself. To remove an entry, you must be able to modify the directory, which requires write permission on the directory. You also need execute permission on the directory to access or traverse it and reach the entry you want to delete. The file’s own permissions don’t control whether you can delete it. (Note: a sticky bit on a directory, common on shared dirs like /tmp, can restrict deletion of files owned by others even if you have write/execute on the directory.) So, the necessary permissions are write and execute on the directory.
