$show

Returns $false if a command is prefixed with a period (.) to make it quiet, otherwise returns $true.

$show

Example

alias deopme {
  if ($me isop $active) { mode $v2 -o $v1 }
  if ($show) { echo -ag You have been deoped. }
}

In the above example if you call .deopme it will not echo out locally you have been deopped, where it would if you just call deopme.
