Patrick wants to change the file permission of a file with permission value 755 to 744. He used a Linux command chmod [permission Value] [File Name] to make these changes. What will be the change in the file access?
Correct Answer: A
In Linux file permissions, the numerical value 755 represents the permissions rwxr-xr-x, where 'r' stands for read, 'w' for write, and 'x' for execute. The first digit '7' corresponds to the file owner's permissions, allowing read, write, and execute. The second and third digits '5' and '5' correspond to the group and others' permissions, allowing read and execute. Changing the permission to 744 changes the group and others' permissions to read only (r-), removing the execute permission. References: This explanation is based on standard Linux permission conventions and the use of the chmod command to change file permissions1.
