7675 :: echo () vs echo()

• masiarek2 (orginal) [2021-03-21T21:24:40+01:00] view original

  echo ()

  echo()

  echo ()

  produces this:

  ()

  ()

  Is it consistent with SOMETHING? We get two pairs of brackets (first and third). Why the middle one (second) is not producing anything? Why is first producing ().

  echo () means "call echo with an empty tuple"

  echo() means "call echo with no arguments"
