Thanks aigles


But my requirement is to match only whole word , Not a subpattern and thus is think that following is sufficient

VALUE="(ABC, DEF, NMF, ABC, CLF, PAR, FHG, AGQSAs, sada, sa, ABC)"
mFlag=`echo $VALUE | egrep -c 'ABC|PAR'`
echo "mFlag = "$mFlag

If you want to test for the entire value, you must modify the egrep RE:

Code:
VALUE="(ABC, DEF, NMF, ABC, CLF, PAR, FHG, AGQSAs, sada, sa, ABC)"
mFlag=`echo $VALUE | egrep -c '[(, ](XXX|GQS)([),]|$)'`
echo "mFlag = "$mFlag

The result will be 0 since there is no element equal to GQS nor XXX inside VALUE

par::packer

PAR::Packer(3pm)					User Contributed Perl Documentation					  PAR::Packer(3pm)

NAME

       PAR::Packer - PAR Packager

DESCRIPTION

       This module implements the App::Packer::Backend interface, for generating stand-alone executables, perl scripts and PAR files.

       Currently, this module is used by the command line tool pp internally, as well as by the contributed contrib/gui_pp/gpp program.

       Since version 0.97 of PAR, this module and its related tools such as "pp" have been stripped from the PAR distribution and are now
       distributed as the "PAR-Packer" distribution so that PAR users need not necessarily have a C compiler.

SEE ALSO

       PAR, pp

       App::Packer, App::Packer::Backend

ACKNOWLEDGMENTS

       Mattia Barbon for taking the first step in refactoring pp into App::Packer::Backend::PAR, and Edward S. Peschko for continuing the work
       that eventually became this module.
