Configure a system to allow files to be shared amongst Linux computers. Create three shares: one called Cheese that is read-only and restricted to the 192.168.1.0/24 network, one called Pickle with read-write access, that permits root privileges and can only be accessed from 192.168.1.1 and one called Crackers that is accessible to 192.168.1.1/24 to 192.168.1.10/24 as read-write and everyone else as read-only. Ensure that all of these files are shared across an array of 2 disks for reliability. Where additional data may be needed to complete this task, generate this using your own judgment.
I want a script in ubuntu
In that script, I need to configure and set up share and set up privileges

a. A, C(R⋈B=1S)
b. A(B = 1R)XC(B = 1S)
c. A, C (ARXB = 1S)
Two of the three expressions are equivalent (i.e., they produce the same answer on all databases), while one of them can produce a different answer
- Which query can produce a contrasting answer? Give the simplest database instance you can think of where a different answer is produced
- Why do we care that the expressions are equivalent?
- How can we determine that the expressions are equivalent?
