one liner needed

Hi

I have a file say (a.txt) which has following

a.txt
----

$$var1=Tom
$$var2=Kim

I need a one liner which searches the file(a.txt) for $$var1 and returns the value in it(Tom).

Thanks in advance
Ammu

Version 0.01 SYNOPSIS
'include' is an opt-in command for you App::Rad programs (myapp.pl): use App::Rad qw(include); # add the 'include' command App::Rad->run(); and now you can turn your one-liners (e.g:) [user@host]$ perl -i -pe 's/ //' file.txt into nice scalable commands, simply replacing 'perl' for 'yourapp include <NAME>' [user@host]$ myapp.pl include dos2unix -i -pe 's/ //' and there you go, a brand new 'dos2unix' command: [user@host]$ myapp.pl dos2unix file.txt DESCRIPTION
This is an internal module for App::Rad and should not be used separately. Please refer to App::Rad for further documentation. INTERNAL METHODS
