What command can an administrator use to fix permissions for a user unable to save a file in their home directory?

• A. chmod 777 /home/Ann
• B. chmod 755 /home/Ann
• C. chmod 744 /home/Ann
• D. chmod 754 /home/Ann

Answer: (D)

The most suitable command for fixing permissions in this context is to use "chmod 754 /home/Ann." This command sets specific permissions for the home directory of the user, Ann, which is critical for enabling her to save files without compromising security. In the command "chmod 754," the permissions are divided into three segments: the first digit (7) allows the owner of the directory to read, write, and execute; the second digit (5) grants read and execute permissions to the group; and the third digit (4) gives read permission to others. This configuration ensures that Ann has full control over her directory, while still allowing others to read but not modify or execute files, striking the right balance between functionality and security. Using this command would typically resolve issues where a user is unable to save files due to inadequate permissions, as it enables necessary access while maintaining a level of security against unauthorized modifications by users outside her group.
