@aucun50:

if (!$2) is the same as if ($2 == $null) just shorter

wrong!!

mabe can be used in this case but "!$1" and "$1 == $null" r not same

look try this

alias test {
  if ($1 == $null) echo 4 -a null
  elseif (!$1) echo 4 -a false
  else echo 3 -a true
}

type:

/test
/test 0
/test 1

and see what i try to tell u.

return

null
false
true
