The gnu sed has -i for update in place. You can just say:
Code:
find ${Appl_Path} -type f -name '*.properties' | while read i
 do
  sed -i '
    s/aaa/'"'"'DEV'"'"'/g
    s/bbb/'"'"'QA'"'"'/g
    s/ccc/'"'"'PROD'"'"'/g
   ' $i
 done

Nothing is meta in ' land, so leave for " land; a single quote in a single quoted string is single-double-single-double-single; I guess I just don't like barefoot \'. Single quotes saves the shell and unwary programmer from any interpretation. Also go to " land for $variables, then come back. Flie globbing is barefoot time.

You, too, deserve nicely indented code where the sed-isms are on different lines than the shell-isms. It prevents bugs and makes maintenance more error-free.

ppi::token::quote::double

PPI::Token::Quote::Double(3)				User Contributed Perl Documentation			      PPI::Token::Quote::Double(3)

NAME

       PPI::Token::Quote::Double - A standard "double quote" token

INHERITANCE

	 PPI::Token::Quote::Double
	 isa PPI::Token::Quote
	     isa PPI::Token
		 isa PPI::Element

DESCRIPTION

       A "PPI::Token::Quote::Double" object represents a double-quoted interpolating string.

       The string is treated as a single entity, PPI will not try to understand what is in the string during the parsing process.

METHODS

       There are several methods available for "PPI::Token::Quote::Double", beyond those provided by the parent PPI::Token::Quote, PPI::Token and
       PPI::Element classes.

       Got any ideas for methods? Submit a report to rt.cpan.org!

   interpolations
       The interpolations method checks to see if the double quote actually contains any interpolated variables.

       Returns true if the string contains interpolations, or false if not.

   simplify
       For various reasons, some people find themselves compelled to have their code in the simplest form possible.

       The "simply" method will turn a simple double-quoted string into the equivalent single-quoted string.

       If the double can be simplified, it will be modified in place and returned as a convenience, or returns false if the string cannot be
       simplified.
