A Linux administrator needs to correct the permissions of a log file on the server. Which of the following commands should be used to set filename.log permissions to -rwxr—r--. ?
D. chmod 744 filename.log
The chmod command is used to change the permissions of files in Linux. The number passed to chmod specifies the binary representation of the desired permissions. The binary representation of -rwxr—r-- is 111 100 100, which corresponds to the decimal value 744. So, the command to set the permissions to -rwxr—r-- is "chmod 744 filename.log".
