Can someone please help me to learn how to deal with loops, arrays and grep?
I have two arrays (lets say I and j) each in a separate file
Quote:
Ruby, Kate, Askley, John ....
Smith, Brown, Green, Casey, ...
And have file with lines of data I need to extract, such as
Ruby Smith: some text here
Ruby Smith: some other text here
Ruby Brown: some text here
Ruby Green: some text here
And I need each of these names into one new file; so each name category will have its own file
Now sure what I think is the right thing and I don't know the syntax... so would appreciate your help
Would something like this even work? How is it going to know what is my “I” and “J” when they are in my files? Should I give a file name?
and I wonder whether the $1file will increase as well? or shall I write something to add that as well?

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

-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

-t
--trace Turn on invoke/execute tracing, enable full backtrace.
-v
--verbose Log message to standard output (default).
--rules Trace the rules resolution.
