Search and Replace in multiple files

Hello,

I have hundreds of files in which I need to change email address. Here is what I am trying to do:

1. All text files are in a directory "a"
2. In the text file, I want to replace email address for preparer. All these lines start with {{PreparerEmail and end with }}. The email addresses on these files are different.

for e.g.
Code:
Line in file1 is
{{PreparerEmail abc@abc.com}}
Line in file2 is
{{PreparerEmail bcd@xyz.com}}
Line in file 3 is
{{PreparerEmail pqr@yyy.com}}

3. I want to replace these emails in all the files within a directory with a common email address for e.g aaa@bbb.com
The expected end result for the sample lines provided earlier would be
Code:
Line in file1 is
{{PreparerEmail aaa@bbb.com}}
Line in file2 is
{{PreparerEmail aaa@bbb.com}}
Line in file 3 is
{{PreparerEmail aaa@bbb.com}}

Any assistance is greatly appreciated.

Log::Dispatch::Email(3) 				User Contributed Perl Documentation				   Log::Dispatch::Email(3)

NAME
Log::Dispatch::Email - Base class for objects that send log messages via email SYNOPSIS
package Log::Dispatch::Email::MySender use Log::Dispatch::Email; use base qw( Log::Dispatch::Email ); sub send_email { my $self = shift; my %p = @_; # Send email somehow. Message is in $p{message} } DESCRIPTION
This module should be used as a base class to implement Log::Dispatch::* objects that send their log messages via email. Implementing a subclass simply requires the code shown in the SYNOPSIS with a real implementation of the "send_email()" method. CONSTRUCTOR
The constructor takes the following parameters in addition to the standard parameters documented in Log::Dispatch::Output: o subject ($) The subject of the email messages which are sent. Defaults to "$0: log email" o to ($ or @) Either a string or a list reference of strings containing email addresses. Required. o from ($) A string containing an email address. This is optional and may not work with all mail sending methods. o buffered (0 or 1) This determines whether the object sends one email per message it is given or whether it stores them up and sends them all at once. The default is to buffer messages. METHODS
o send_email(%p) This is the method that must be subclassed. For now the only parameter in the hash is 'message'. o flush If the object is buffered, then this method will call the "send_email()" method to send the contents of the buffer and then clear the buffer. o DESTROY On destruction, the object will call "flush()" to send any pending email.
