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

app::rad::include
App::Rad::Include(3pm) User Contributed Perl Documentation App::Rad::Include(3pm)
NAME
App::Rad::Include - 'include' command extension for App::Rad
VERSION
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
load
Loads the module into App::Rad
include
Translates perl one-liner into self-contained command (subroutine) and adds it to your App::Rad program.
DEPENDENCIES
o O, which is core in Perl 5.8.
o B::Deparse, also core in 5.8.
o Perl::Tidy (optional)
AUTHOR
Breno G. de Oliveira, "<garu at cpan.org>"
ACKNOWLEDGEMENTS
The one-liner conversion and beautification was *much* easened because of the nice "O" , "B::Deparse" and "Perl::Tidy" modules. So many
thanks to Malcolm Beattie, Nicholas Clark, Stephen McCamant, Steve Hancock, and everyone that helped those projects.
