Exclamation Comparing all the files in a directory, by content.


I wish to compare all the files in a directory....comparing is by content. And same files should be printed....

echo "program : $0"

cd $1

for a in *
do
for b in *
do
diff -as $a $b > /dev/null
if [ $? -eq 0 ];
then
echo "$a and $b in $1 same..."
fi
done
done

This logic did not give the correct result....please help...!!!

Please put your code in CODE tags. And have you checked your other thread, where you ask the same question, and have gotten replies?

NO...NO....
In previous thread I was comparing files in two different directories.....

In the second thread I wish to compare all the files within the a single directory.....eg

Directory---d1
contains files f1, f2, f3, ....fn....I have to print which files have same content....

Code:
#!/usr/bin/env ruby -w
require 'digest'
def getdigest(file)
   Digest::MD5.hexdigest(File.open(file, "rb") { |f| f.read })
end

hash = Hash.new { |h,k| h[k]="" }
Dir["*"].each do
  |x|
  File.file?(x) and hash[x]=getdigest(x)
end
u=hash.values.uniq
v=hash.values
u.each do
  |z|
  col=[] #to collect identical
  if v.count(z) > 1
      hash.each{|x,y| col<<x if y==z}
  end
  print  "These files are identical: #{col.join(" ")}\n" if !col.empty?
end

Ok, so why can't you modify that code to read from the same directory?? And this sounds very much like a homework question...
