Full Discussion: Difference between [condition] and [[condition]] and ((condition)) when used with if condition
Operating Systems HP-UX Difference between [condition] and [[condition]] and ((condition)) when used with if condition Post 302520133 by frank_rizzo on Friday 6th of May 2011 12:16:48 AM

inside [] or [[]] use -gt/-eq/-lt/etc... [[]] might be safe because it's built into the shell but you should use the proper operators.

inside (()) values will be treated as numeric. see also let


also - please use CODE tags around the logic.

exacct::object::group

Exacct::Object::Group(3PERL)				      Perl Library Functions				      Exacct::Object::Group(3PERL)

NAME

       Exacct::Object::Group - exacct group manipulation

SYNOPSIS

       use Sun::Solaris::Exacct::Object;
       my $ea_grp = Sun::Solaris::Exacct::Object::Group->new(
	  & EXT_GROUP | &EXC_DEFAULT | &EXD_GROUP_PROC);

DESCRIPTION

       This  module is used for manipulating libexacct(3LIB) Group objects. A libexacct Group object is represented as an opaque reference blessed
       into the Sun::Solaris::Exacct::Object::Group class, which is a subclass of the Sun::Solaris::Exacct::Object class. The Items within a Group
       are  stored  inside a Perl array. A reference to the array can be accessed with the inherited value() method. The individual Items within a
       Group can be manipulated with the normal Perl array syntax and operators. All  data  elements  of  the  array  must  be	derived  from  the
       Sun::Solaris::Exacct::Object class.  Group objects can also be nested inside each other simply by adding an existing Group as a data Item.

   Constants
       None.

   Functions
       None.

   Class methods
       Class methods include those inherited from the Sun::Solaris::Exacct::Object base class, plus the following:

       new($catalog, @objects)

	   This  method  creates  and  returns	a  new	Sun::Solaris::Exacct::Object::Group.  The  catalog  tag  can  be  either  an  integer or a
	   Sun::Solaris::Exacct::Catalog. The catalog tag should be a valid catalog tag for a Perl exacct Group object. The @objects parameter	is
	   a list of Sun::Solaris::Exacct::Object to be stored inside the Group. A copy of all the passed Items is taken and any Group objects are
	   recursively copied. The contents of the returned Group object can be accessed with the array returned by the value method.

   Object methods
       as_hash()

	   This method returns the contents of the group as a hash reference. It uses the string value of each item's catalog ID as the hash entry
	   key	and the scalar value returned by value() as the hash entry value. This form should be used if  there are no duplicate catalog tags
	   in the group.

	   This method and its companion as_hashlist() are the fastest ways to access the contents of a Group.

       as_hashlist()

	   This method returns the contents of the group as a hash reference. It uses the string value of each item's catalog id as the hash entry
	   key	and an array of the scalar values returned by value() as the hash entry value for all the items that share a common key. This form
	   should be used if there might be duplicate catalog tags in the group.

	   This method and its companion as_hash() are the fastest ways to access the contents of a Group.

   Exports
       None.
