A user is unable to access certain files fram a specific folder. Which of the following commands should a technician use to modify the file permissions for a specific file?

Question

Options

• Achown
• Bls
• Cgrep
• Dcp

• A
  93% (26)
• C
  4% (1)
• D
  4% (1)

Explanation

Among the listed options, chown (change owner) is the Linux/Unix command most directly related to file access control - it changes the ownership (user and/or group) of a file, which directly affects who holds access rights. Note that chmod is the more precise command for modifying read/write/execute permission bits, but it is not among the choices. The remaining options - ls (list directory contents), grep (search text patterns), and cp (copy files) - have no role in managing file permissions or ownership. On an exam where chmod is absent, chown is the best available answer.
