To get you started, first check that you can find the files with a command like this:
Please post you Operating System and version and what Shell you use.
As @elixir_sinari implies there could be a pure Shell approach using file pattern matching and the test -s command . If you need to search the tree, find is preferred.
I you need further help, please remember to describe your directory tree.
Hi,
I've modified the syslogd source to include a thread that will keep track of a timer(or a timer thread).

tree::simple::visitor::findbynodevalue
Tree::Simple::Visitor::FindByNodeValue(3pm) User Contributed Perl Documentation Tree::Simple::Visitor::FindByNodeValue(3pm)NAME
Tree::Simple::Visitor::FindByNodeValue - A Visitor for finding an element in a Tree::Simple hierarchy by node value
SYNOPSIS
use Tree::Simple::Visitor::FindByNodeValue;
# create a visitor object
my $visitor = Tree::Simple::Visitor::FindByNodeValue->new();
# set the search path for our tree
$visitor->searchForNodeValue("My Tree Node");
# pass the visitor to a tree
$tree->accept($visitor);
# fetch the result, which will
# be the Tree::Simple object that
# we have found, or undefined
my $result = $visitor->getResult() || die "No Tree found";
DESCRIPTION
Given a node value and Tree::Simple hierarchy, this Visitor will attempt to find the node with the same node value.
METHODS
new There are no arguments to the constructor the object will be in its default state. You can use the "setNodeFilter",
"setTraversalMethod", "includeTrunk" and "searchForNodeValue" methods to customize its behavior.
includeTrunk ($boolean)
Based upon the value of $boolean, this will tell the visitor to include the trunk of the tree in the search as well.
setTraversalMethod ($visitor)
By default we will use Tree::Simple's built in depth-first (pre-order) traverse method. If however, you desire the tree to be search in
a different ordering, this can be accomplished using a different traversal method, you can supply a $visitor object implementing that
traversal type to this method (See Tree::Simple::Visitor::BreadthFirstTraversal, Tree::Simple::Visitor::PreOrderTraversal and
Tree::Simple::Visitor::PostOrderTraversal).
searchForNodeValue ($node_value)
This is the node value we will attempt to find within the tree.
setNodeFilter ($filter_function)
This method accepts a CODE reference as its $filter_function argument and throws an exception if it is not a code reference. This code
reference is used to further check the tree nodes as they are searched and so can be used to customize search behavior. For instance,
you could to check against the node value as well as some other criteria. The filter function should accept a single argument, which is
the current Tree::Simple object and return either true(1) on success, or false(0) on failure.
visit ($tree)
This is the method that is used by Tree::Simple's "accept" method. It can also be used on its own, it requires the $tree argument to be
a Tree::Simple object (or derived from a Tree::Simple object), and will throw and exception otherwise.
getResult
This method will return the tree found with the specified node value (set by the "searchForNodeValue" method) or "undef" if no tree is
found.
BUGS
None that I am aware of. Of course, if you find a bug, let me know, and I will be sure to fix it.
CODE COVERAGE
See the CODE COVERAGE section in Tree::Simple::VisitorFactory for more inforamtion.
SEE ALSO
These Visitor classes are all subclasses of Tree::Simple::Visitor, which can be found in the Tree::Simple module, you should refer to that
module for more information.
