echo "$("pwd")"
echo "$X"
exec python py.py "$(X)"

py.py
Code:
#!/usr/local/bin/python
import os
print "Now, we're going to add up some numbers."

rake

RAKE(1) 						 Ruby Programmers Reference Guide						   RAKE(1)

NAME

     rake -- Ruby Make

SYNOPSIS

     rake [--f Rakefile] [--version] [-CGNPgnqstv] [-D [PATTERN]] [-E CODE] [-I LIBDIR] [-R RAKELIBDIR] [-T [PATTERN]] [-e CODE] [-p CODE]
	  [-r MODULE] [--rules] [variable=value] target ...

DESCRIPTION

     Rake is a simple ruby(1) build program with capabilities similar to the regular make(1) command.

     Rake has the following features:

     o	 Rakefiles (Rake's version of Makefiles) are completely defined in standard Ruby syntax.  No XML files to edit. No quirky Makefile syntax
	 to worry about (is that a tab or a space?).

     o	 Users can specify tasks with prerequisites.

     o	 Rake supports rule patterns to synthesize implicit tasks.

     o	 Flexible FileLists that act like arrays but know about manipulating file names and paths.

     o	 A library of prepackaged tasks to make building rakefiles easier.

OPTIONS

     --version		 Display the program version.

     -C
     --classic-namespace
			 Put Task and FileTask in the top level namespace

     -D [PATTERN]
     --describe [PATTERN]
			 Describe the tasks (matching optional PATTERN), then exit.

     -E CODE
     --execute-continue CODE
			 Execute some Ruby code, then continue with normal task processing.

     -G
     --no-system
     --nosystem 	 Use standard project Rakefile search paths, ignore system wide rakefiles.

     -I LIBDIR
     --libdir LIBDIR	 Include LIBDIR in the search path for required modules.

     -N
     --no-search
     --nosearch 	 Do not search parent directories for the Rakefile.

     -P
     --prereqs		 Display the tasks and dependencies, then exit.

     -R RAKELIBDIR
     --rakelib RAKELIBDIR
     --rakelibdir RAKELIBDIR
			 Auto-import any .rake files in RAKELIBDIR.  (default is rakelib )

     -T [PATTERN]
     --tasks [PATTERN]	 Display the tasks (matching optional PATTERN) with descriptions, then exit.

     -e CODE
     --execute CODE	 Execute some Ruby code and exit.

     -f FILE
     --rakefile FILE	 Use FILE as the rakefile.

     -h
     --help		 Prints a summary of options.

     -g
     --system		 Using system wide (global) rakefiles (usually ~/.rake/*.rake ).

     -n
     --dry-run		 Do a dry run without executing actions.

     -p CODE
     --execute-print CODE
			 Execute some Ruby code, print the result, then exit.

     -q
     --quiet		 Do not log messages to standard output.

     -r MODULE
     --require MODULE	 Require MODULE before executing rakefile.

     -s
     --silent		 Like --quiet, but also suppresses the 'in directory' announcement.

     -t
     --trace		 Turn on invoke/execute tracing, enable full backtrace.

     -v
     --verbose		 Log message to standard output (default).

     --rules		 Trace the rules resolution.
