- Write the command that will locate all files that are larger than 10 megabytes in size, and copy each one to the directory "/overflow".There is no real difference between the “S” and “s” special permissions when displayedusing the ls –l command. One just means it is on a file, and the other means that it ison a directory. True or False?After typing the ls –F command, you see the following line in the output:-rw-r-xr- - 1 user1 root 0 Apr 29 15:40 file1What does this mean?a. User1 has read and write, members of the root group have read and execute, and allothers have read permissions to the file.b. Members of the root group have read and write, user1 has read and execute, and allothers have read permissions to the file.c. All users have read and write, members of the root group have read and execute,and user1 has read permissions to the file.d. User1 has read and write, all others have read and execute, and members of theroot group have read permissions to the file.
