-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

prune

prune(1)						      General Commands Manual							  prune(1)

NAME

       prune - Prune directed graphs

SYNOPSIS

       prune [ -n node ] [ -N attrspec ] [ files ...  ]

DESCRIPTION

       prune  reads  directed  graphs  in  the	same format used by dot(1) and removes subgraphs rooted at nodes specified on the command line via
       options. These nodes themselves will not be removed, but can be given attributes so that they can be easily located by a graph stream  edi-
       tor such as gvpr(1).  prune correctly handles cycles, loops and multi-edges.

       Both options can appear multiple times on the command line. All subgraphs rooted at the respective nodes given will then be processed. If a
       node does not exist, prune will skip it and print a warning message to stderr.  If multiple attributes are given, they will be  applied	to
       all nodes that have been processed.  prune writes the result to the stdout.

OPTIONS

       -n name
	      Specifies name of node to prune.

       -N attrspec
	      Specifies attribute that will be set (or changed if it exists) for any pruned node.  attrspec is a string of the form attr=value.

EXAMPLES

       An input graph test.dot of the form

	    digraph DG {
	      A -> B;
	      A -> C;

	      B -> D;
	      B -> E;
	    }

       , processed by the command

	    prune -n B test.dot

       would produce the following output (the actual code might be formatted in a slightly different way).

	    digraph DG {
	      A -> B;
	      A -> C;
	    }

       Another input graph test.dot of the form

	    digraph DG {
	      A -> B;
	      A -> C;

	      B -> D;
	      B -> E;

	      C -> E;
	    }

       (note the additional edge from C to E ), processed by the command

	    prune -n B -N color=red test.dot

       results in

	    digraph DG {
	      B [color=red];
	      A -> B;
	      A -> C;
	      C -> E;
	    }

       Node E has not been removed since its second parent C is not being pruned.

EXIT STATUS

       prune returns 0 on successful completion.  It returns 1 if an error occurs.
