Hi
I have 2 questions:
Q1 - What does
${1:+$1/}*
mean? I guess it lists all files in current directory - Could any one explain how this expression works?
Q2 - I am trying to list directories only in current path - I know that ls could be used but I thought I'd give find a try. I need to... (5 Replies)
Hi,
Simple question.
If i could find a file been listed in many dirctories, how to get the unique list of directories.
find / -name "abc*" --> will give me list of directories.
/home/abc.txt
/home/ddd/abcd.txt
/home/ddd/abcde/txt
So how to get
/home
/home/ddd
Thanks in... (2 Replies)

Hello all!
I'm looking to list directories and sub-directories of a path, on this forum I found this command:
find $path -type d -exec ls -ld {} \;
The issue I have is that with a simple ls, the list is listed by name, and using -t I get it by time.
How could I list directories and sub... (5 Replies)
How can I find and print the directories on a server that have more than 5,000 files? There's some spam emails and I'm trying to find all directories that have a lot of spam
The file count should just be the files directly under that directory, not like the total from all nested directories

Tree::Simple::Visitor::PostOrderTraversal(3pm) User Contributed Perl Documentation Tree::Simple::Visitor::PostOrderTraversal(3pm)NAME
Tree::Simple::Visitor::PostOrderTraversal - A Visitor for post-order traversal a Tree::Simple hierarchy
SYNOPSIS
use Tree::Simple::Visitor::PostOrderTraversal;
# create an visitor
my $visitor = Tree::Simple::Visitor::PostOrderTraversal->new();
# pass our visitor to the tree
$tree->accept($visitor);
# print our results
print join ", " => $visitor->getResults();
# this will print this:
# 1.1.1 1.1 1.2 1 2.1 2 3.1 3
# assuming your tree is like this:
# 1
# 1.1
# 1.1.1
# 1.2
# 2
# 2.1
# 3
# 3.1
DESCRIPTION
Post-order traversal is a variation of the depth-first traversal in which the sub-tree's are processed before the parent. It is another
alternative to Tree::Simple's "traverse" method which implements a depth-first, pre-order traversal.
METHODS
new There are no arguments to the constructor the object will be in its default state. You can use the "setNodeFilter" method to customize
its behavior.
includeTrunk ($boolean)
Based upon the value of $boolean, this will tell the visitor to include the trunk of the tree in the traversal as well.
setNodeFilter ($filter_function)
This method accepts a CODE reference as its $filter_function argument and throws an exception if it is not a code reference. This code
reference is used to filter the tree nodes as they are collected. This can be used to customize output, or to gather specific
information from a more complex tree node. The filter function should accept a single argument, which is the current Tree::Simple
object.
visit ($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.
getResults
This method returns the accumulated results of the application of the node filter to the tree.
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.
