In the permission string rwx rwx rwx, what does this indicate for user, group, and others?

• A. Read and execute only
• B. Write and execute only
• C. Full read, write, and execute for all three categories
• D. No permissions

Answer: (C)

In Linux, a permission string is shown in three triplets, each corresponding to user (owner), group, and others. Each position within a triplet can be r (read), w (write), or x (execute), or a dash if that permission is missing. If the string is rwx rwx rwx, it means every category—user, group, and others—has all three permissions: read, write, and execute. For a file, that means anyone can read the file, modify it, and run it if it’s executable; for a directory, it means anyone can list, modify, and traverse into that directory. This is why it represents full permissions for all three categories.
