Substring using sed or awk
I am trying to get a substring from a string stored in a variable. I tried sed with a bit help from this forum, but not successful. Here is my problem.

My string is: "REPLYFILE=myfile.txt"
And I need: myfile.txt (everything after the = symbol).

My string is: "myfile.txt.gz.20091120.enc
And I need: myfile.txt.gz (everything before string .gz, including .gz).

After my sed failed, I tried to get the position of the delimiting string thinking of using cut command. But failed at that as well.

As I am trying to learn sed and awk, any links to good tutorial is appreciated.
Thanks

tpage

TPAGE(1)						User Contributed Perl Documentation						  TPAGE(1)

NAME

       Template::Tools::tpage - Process templates from command line

USAGE

	   tpage [ --define var=value ] file(s)

DESCRIPTION

       The tpage script is a simple wrapper around the Template Toolkit processor.  Files specified by name on the command line are processed in
       turn by the template processor and the resulting output is sent to STDOUT and can be redirected accordingly.  e.g.

	   tpage myfile > myfile.out
	   tpage header myfile footer > myfile.html

       If no file names are specified on the command line then tpage will read STDIN for input.

       The "--define" option can be used to set the values of template variables.  e.g.

	   tpage --define author="Andy Wardley" skeleton.pm > MyModule.pm

       See Template for general information about the Perl Template Toolkit and the template language and features.
