Thanks the above works very nicley. But i now have another issue.
I need to efficiently scan through a text file of 70,000 lines and populate an array. This time it is more complex. Each line has 5 numbers, and is comma separated; EL_Num, Node_A, Node_B, Node_C, Node_D. The values for these are all integers.
I want to populate the array with the index equal to the Node number, and the string equal to all the El_num which contain that node.
For example given the below lines out of the file:
It can be seen that all el_num contain node 5018.
Therefore ARRAY[5108] should equal 5014, 5015, 5016.
Like wise ARRAY[5249] should equal 5014
I have a method below but it is very slow, how can this be done efficiently?

Hi,
I am not so familiar with bash scripting and would appreciate your help here.
I have a text file 'input.txt' like this:

I want to store each column in an array like this
a ={2 5 8}, b={3 6 9}, c={4 7 10}

tree::simple::visitor::pathtoroot
Tree::Simple::Visitor::PathToRoot(3pm) User Contributed Perl Documentation Tree::Simple::Visitor::PathToRoot(3pm)NAME
Tree::Simple::Visitor::PathToRoot - A Visitor for finding the path back a Tree::Simple object's root
SYNOPSIS
use Tree::Simple::Visitor::PathToRoot;
# create an instance of our visitor
my $visitor = Tree::Simple::Visitor::PathToRoot->new();
# pass the visitor to a Tree::Simple object
$tree->accept($visitor);
# now get the accumulated path as a string
# with the '/' character as the delimiter
print $visitor->getPathAsString("/");
# include the tree's trunk in your
# output as well
$visitor->includeTrunk();
# for more complex node objects, you can specify
# a node filter which will be used to extract the
# information desired from each node
$visitor->setNodeFilter(sub {
my ($t) = @_;
return $t->getNodeValue()->description();
});
# you can also get the path back as an array
my @path = $visitor->getPath();
DESCRIPTION
Given a Tree::Simple object, this Visitor will find the path back to the tree's root node.
METHODS
new There are no arguments to the constructor the object will be in its default state. You can use the "includeTrunk" and "setNodeFilter"
methods to customize its behavior.
includeTrunk ($boolean)
Based upon the value of $boolean, this will tell the visitor to collect the trunk of the tree as well.
setNodeFilter ($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 $tree argument to be
a Tree::Simple object (or derived from a Tree::Simple object), and will throw and exception otherwise.
getPath
This will return the collected path as an array, or in scalar context, as an array reference.
getPathAsString ($delimiter)
This will return the collected path as a string with the path elements joined by a $delimiter. If no $delimiter is specified, the
default (', ') will be used.
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.
