file. The size of the my_backup.tgz file is 800MB. Now, he wants to break this file into two files in which the size of the first file
named my_backup.tgz.aa should be 600MB and that of the second file named my_backup.tgz.ab should be 200MB. Which
of the following commands will John use to accomplish his task?

A.
split –verbose -b 200m my_backup.tgz my_backup.tgz

B.
split –verbose -b 200m my_backup.tgz my_backup.tgz

-a, –suffix-length=N
use suffixes of length N (default 2)
-b, –bytes=SIZE
