Solve : Linux Question?

1.	Solve : Linux Question?
Answer» In experimenting with shell VARIABLES, Alex ACCIDENTALLY deletes his PATH variable. He decides that he does not need the PATH variable. Discuss some of the problems he may soon encounter and explain the reasons for these problems. How could he easily return PATH to its original value? This Alex FELLOW sounds like a troublemaker.Too true. The solution in the future would clearly be prevention; Do NOT allow Alex anywhere near the computer. Is this on a Linux Certification Practice Test of some sort? Because I may know the answer, but I refrain from answering due to possible ethical complications.don't WORRY Alex is not the only experimenter. I got in trouble for messing with my family's computer (i was only 11)
