q=3while q = 3 do  echo blah  q=expr $q + 1 doneI am getting ready for an exam and have come across this question. I am confused on what the output will be.I think the output will be an error. The reason being that  while q = 3 should be while q -eq 3 instead.If someone can give me a good explain of this piece of code that would be really nice and helpful.Thank you.
What will the output of this script be?
shell script;shell
