Question

Based on the output of the ls -l command for the file "books_file" in Linux (line 3), what permissions does the second trio of bits (-wx) give you? Check all that apply.

A) Read permission
B) Write permission
C) Execute permission
D) Setuid permission

Answer 1

The second trio of bits (-wx) in the output of the ls -l command indicates the permissions for the group that the file belongs to. In this case, the 'x' indicates that the members of the group have execute permission on the file.

Step-by-step explanation:

Based on the output of the ls -l command for a file in Linux, the second trio of bits (-wx) corresponds to the permissions for the group that the file belongs to. In this specific case, the second trio of bits gives the group write permission (B) and execute permission (C), but not read permission. Setuid permission (D) is indicated by a special bit that is not part of the regular permission trios.

The second trio of bits (-wx) in the output of the ls -l command for the file "books_file" in Linux indicates the permissions for the group that the file belongs to. Each trio of bits represents the permissions for the owner, group, and others respectively.

The letters 'r', 'w', and 'x' represent read, write, and execute permissions respectively. In this case, the 'x' in the second trio of bits indicates that the members of the group have execute permission on the file. This means they can run the file if it is an executable program or script.

Therefore, the correct answer is C) Execute permission.
