With GNU grep:
Code:
grep -o "IpCore Version : IPCORE_A.02.12.00011" "$FILE"

But if you know what you wnat, all you need is to check whether it is in the file:

Code:
string="IpCore Version : IPCORE_A.02.12.00011"
if grep "$string" > /dev/null
then
  printf "%s\n" "$string"
else
  printf "'%s' not found\n" "$string"
fi

DH_INSTALLEMACSEN(1)						     Debhelper						      DH_INSTALLEMACSEN(1)

NAME

       dh_installemacsen - register an Emacs add on package

SYNOPSIS

       dh_installemacsen [debhelperoptions] [-n] [--priority=n] [--flavor=foo]

DESCRIPTION

       dh_installemacsen is a debhelper program that is responsible for installing files used by the Debian emacsen-common package into package
       build directories.

       It also automatically generates the preinst postinst and prerm commands needed to register a package as an Emacs add on package. The
       commands are added to the maintainer scripts by dh_installdeb. See dh_installdeb(1) for an explanation of how this works.

FILES

       debian/package.emacsen-compat
	   Installed into usr/lib/emacsen-common/packages/compat/package in the package build directory.

       debian/package.emacsen-install
	   Installed into usr/lib/emacsen-common/packages/install/package in the package build directory.

       debian/package.emacsen-remove
	   Installed into usr/lib/emacsen-common/packages/remove/package in the package build directory.

       debian/package.emacsen-startup
	   Installed into etc/emacs/site-start.d/50package.el in the package build directory. Use --priority to use a different priority than 50.

OPTIONS

       -n, --no-scripts
	   Do not modify postinst/prerm scripts.

       --priority=n
	   Sets the priority number of a site-start.d file. Default is 50.

       --flavor=foo
	   Sets the flavor a site-start.d file will be installed in. Default is emacs, alternatives include xemacs and emacs20.

NOTES

       Note that this command is not idempotent. dh_prep(1) should be called between invocations of this command. Otherwise, it may cause multiple
       instances of the same text to be added to maintainer scripts.

       This program is a part of debhelper.
