You can use GNU grep, or you can use perl, which is easiest I think. This prints out ONLY the ABCDDIR text when found:

Code:

perl -n -e '/ABCDDIR/i && print $&,"\n";'

In this case, you can use perl instead of sed -- this prints out the original text as you want it:

Code:

perl -p \
-e "s+ABCDIR+$DDIR/C+gi" \
-e "s+ABCDIR+$DDIR/C+gi" \
-e "s+ABCDDIR+$DDIR/C+gi"

PAR::Filter::Bytecode(3pm)				User Contributed Perl Documentation				PAR::Filter::Bytecode(3pm)

NAME

       PAR::Filter::Bytecode - Bytecode filter

SYNOPSIS

	   PAR::Filter::Bytecode->apply($code); # transforms $code

DESCRIPTION

       This filter is deprecated. The B::Bytecode code has been removed from the newest development series of perl and will not be included in
       perl 5.10 any more. Please have a look at Steve Hay's PAR::Filter::Crypto module if you want to hide your sources.

       This filter uses B::Bytecode to turn the script into comment-free, architecture-specific Perl bytecode, and uses ByteLoader to load back on
       execution.

       For pp users, please add an extra -M option, like this:

	   pp -f Bytecode -M ByteLoader

       Otherwise, the implicit dependency on ByteLoader will not be detected.

CAVEATS

       This backend exhibits all bugs listed in B::Bytecode, and then some.

       Bytecode support is considered to be extremely fragile on Perl versions earlier than 5.8.1, and is still far from robust (as of this
       writing).

       Bytecode is not supported by perl 5.9 and later.
