I want to write command line Ruby program whose arguments will be a
list of words to be found within all HTML documents of the current
directory. The output of the program will be a text file called
results.txt and will consist of a list of all HTML documents in which
one of the words appeared. Have the program create a subdirectory
called FINAL ,of the current directory and save results.txt there.
Finally, it will make duplicate copies of each of the files listed in
results.txt within the FINAL directory.
Any help would be greatly appreciated

It’s awfully late in the semester for your professor to be making new
programming assignments, isn’t it? 
system(%q!sh “list=‘word1 word2 …’; mkdir -p FINAL; for a in list; do for f in *.html; do grep $a $f >/dev/null && echo $f >> FINAL/results.txt && cp $f FINAL; done; done”!)
I think

something like this could work
#lil code, missing excepetion handling, one time runnable 
Dir.mkdir(“./FINAL”)
File.open (“FINAL/result.txt”, “w+”) { |out|
Dir[“*.html”].each { |file|
IO.foreach(file) { |f|
out.puts file if f =~ /#{ARGV.join(“|”)}/
}
}
}
IO.foreach “FINAL/result.txt” { |line|
system(“mv #{line.chomp} FINAL/”)
}
#should handle this to be xplatform
Is nice whane you don’t follow a Ruby programing course and get the
homework anyway

George,
Here’s my try at it; AKAIK it’s platform independent. Note I included regex
support.
[Calling the script multiple times with different arguments will screw up the
results-- FINAL should be deleted after every use-- this can be added to the
script.]
···
#!/usr/bin/ruby -w
require ‘ftools’
DIR = ‘FINAL’
RESULTS = File::join DIR, ‘results.txt’
class PageHarvest
def initialize words
@matches =
Dir[‘*.htm?’].each do |file|
data = File::read file # for 1.6.7: File::open(file){ |f| f.read }
words.each do |word|
if not @matches.include?(file)
# change below to: data.include?(word)
# if you don’t want regexes
@matches << file if data =~ /#{word}/
end
end
end
finalize unless @matches.empty?
end
def finalize
Dir::mkdir(DIR) unless File::directory?(DIR)
File::open(RESULTS, ‘w’) do |results|
@matches.each do |match|
results.puts match
File::copy match, File::join(DIR, match)
end
end
end
end
runtime…
PageHarvest.new(ARGV) if FILE == $0
(and yes, I’m aware it might be a bit much to write a Class for such a simple
thing-- but how could I let a name like ‘PageHarvest’ go to waste?
Hope this helps,

I think it was supposed to be AFAIK, which is “As Far As I Know”
Others you may see:
IIRC - if I recall correctly
AFAICT - as far as I can tell
