Hi radoulov,

when we have given this ([^ ]*\) in our code it will search for any charcter different than space so according to that
our output should be this

CPU Util SSUUUUU | 16% 9% 22%

how its coming to only
CPU

similarly in this part [^0-9]*\([0-9]*%\).*$
we are first searching for any charcter different than 0-9 so the output should be

CPU Util SSUUUUU |

after that it searches for 0-9 with %
so the output should be

16% 9% 22%

and how its coming

16%

and thanks for the earlier response
it cleared many doubts of mine
but still have some doubts that i would like to clear

thanks
haris

hash::util::fieldhash::compat

Hash::Util::FieldHash::Compat(3pm)			User Contributed Perl Documentation			Hash::Util::FieldHash::Compat(3pm)

NAME

       Hash::Util::FieldHash::Compat - Use Hash::Util::FieldHash or ties, depending on availability.

SYNOPSIS

	       use Hash::Util::FieldHash::Compat;

	       # pretend you are using L<Hash::Util::FieldHash>
	       # under older perls it'll be Tie::RefHash::Weak instead (slower, but same behavior)

DESCRIPTION

       Under older perls this module provides a drop in compatible api to Hash::Util::FieldHash using perltie. When Hash::Util::FieldHash is
       available it will use that instead.

       This way code requiring field hashes can benefit from fast, robust field hashes on Perl 5.10 and newer, but still run on older perls that
       don't ship with that module.

       See Hash::Util::FieldHash for all the details of the API.

SEE ALSO

       Hash::Util::FieldHash, Tie::RefHash, Tie::RefHash::Weak.

VERSION CONTROL

       This module is maintained using Darcs. You can get the latest version from <http://nothingmuch.woobling.org/code>, and use "darcs send" to
       commit changes.
