Take a look at Perl's -s option.

Ignoring any quoting issues, something like this should work: 

perl -pi -se 's/.*'def'.*''/\t"def" => "dumper\/$D.def",/g' -D=ADCIF C
+onfigFile

Note: That -D=... becomes $D inside the script.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
