In Linux, what does rwx permission string specify?

• A. User ownership of the file
• B. Group ownership
• C. User, group, and others permissions for read, write, execute
• D. File size in kilobytes

Answer: (C)

The rwx permission string shows who can do what with a file or directory. It’s displayed as three groups of three characters. The first group applies to the file owner (the user), the second to the file’s group, and the third to everyone else (others). Within each group, r stands for read, w for write, and x for execute; a dash means that permission isn’t granted. For example, a typical string like -rwxr-xr-- means the owner can read, write, and execute; the group can read and execute; others can only read. This is why the correct interpretation is that the string specifies user, group, and others permissions for read, write, and execute. The options about ownership or file size don’t describe the permission bits.
