-o switch in find
Hello all

I'm experimenting with the use of the -prune action and I've encountered some confusing behaviour when using the -o option. Can't find anything specific in the man page.

If I have a directory within my current directory called testlink and I run:-

find . -name testlink -prune

I get what I would expect - the name of the directory, but none of the contents, since the -prune switch has prevented the command descending. However, if I run:-

find . -name testlink -prune -o -print

Then all other files/directories in the current one are displayed, but not the testlink directory.

My understanding is that the -o option is a 'short-circuit' OR, in which case, having returned true with the left-hand expression, should the -print action be performed? Also, shouldn't the testlink directory be displayed?

I'm using SunOS 5.5.1, using KSH.

Thanks

xtmenupopdown

XtMenuPopdown() 														   XtMenuPopdown()

Name
  XtMenuPopdown - built-in action for popping down a widget.

Synopsis (Translation Table)
  <Event sequence>: XtMenuPopdown([shell])

Inputs
  shell     An optional argument which specifies the name of the shell to pop down.

Availability
  This action is named MenuPopdown prior to Release 4.

Description
  XtMenuPopdown  is a predefined action procedure which does not have a corresponding public C routine.  It can only be invoked from a trans-
  lation table.  If passed an argument, that argument is interpreted as a shell name, and XtMenuPopdown tries to  find	the  named  shell  by
  looking up the widget tree starting at the parent of the widget in which it is invoked.  If it finds a shell with the specified name in the
  popup children of that parent, it pops down the shell by calling XtPopdown(); otherwise, it moves  up  the  parent  chain  as  needed.   If
  XtMenuPopdown  gets  to the application top-level shell widget and cannot find a matching shell, it generates a warning and returns immedi-
  ately.  If XtMenuPopdown is called with no argument, it calls XtPopdown() on the widget for which the translation is specified.

Usage
  Note that XtMenuPopdown is an action procedure; you cannot call it from C code.

  The action name MenuPopdown is a synonym for XtMenuPopdown.  Either action can be used to pop down menus or other popup shells.

  Popup shells can also be popped down by calling XtPopdown() explicitly, or by using the predefined callback procedure XtCallbackPopdown().

  The action XtMenuPopup can be used to pop up a spring-loaded popup from a translation table.
