Hi All,
I need some help/ideas in coming up with a shell script.
Basically, the script should install 1 or 2 or 3 packages based on the input arguments.
For example, if I type in pkgscript.sh a1 a2 a3, it should install all the 3 scripts and pkgscript.sh a1 should install only a1.

Tree::Simple::Visitor::FindByPath(3pm) User Contributed Perl Documentation Tree::Simple::Visitor::FindByPath(3pm)NAME
Tree::Simple::Visitor::FindByPath - A Visitor for finding an element in a Tree::Simple hierarchy with a path
SYNOPSIS
use Tree::Simple::Visitor::FindByPath;
# create a visitor object
my $visitor = Tree::Simple::Visitor::FindByPath->new();
# set the search path for our tree
$visitor->setSearchPath(qw(1 1.2 1.2.2));
# 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";
# our result's node value should match
# the last element in our path
print $result->getNodeValue(); # this should print 1.2.2
DESCRIPTION
Given a path and Tree::Simple hierarchy, this Visitor will attempt to find the node specified by the path.
METHODS
new There are no arguments to the constructor the object will be in its default state. You can use the "setSearchPath" and "setNodeFilter"
methods to customize its behavior.
includeTrunk ($boolean)
Based upon the value of $boolean, this will tell the visitor to include the trunk of the tree in the search as well.
setSearchPath (@path)
This is the path we will attempt to follow down the tree. We will do a stringified comparison of each element of the path and the
current tree's node (or the value returned by the node filter if it is set).
setNodeFilter ($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.
getResult
This method will return the tree found at the specified path (set by the "setSearchPath" method) or "undef" if no tree is found.
getResults
This method will return the tree's that make up the path specified in "setSearchPath". In the case of a failed search, this can be used
to find the elements which did successfully match along the way.
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.
