How to get the differences between text files

[koduruabhinav]

i have two modules.txt files
module1.txt
module2. txt


i have to comare the conents of files and i have to print the output as folls

module1 module2
.COMPENSATION ( "ZHOLD" ), .COMPENSATION ("EXTERNAL" ),

.CLKIN1_PERIOD ( 5 ), .CLKIN1_PERIOD ( 5.000000 ),


i want the differences to be printed like that
but i was unable

the code i have developed is

my @codes1 = split /\./, $modcode_from_1;(text in module1)
my @codes2 = split /\./, $modcode_from_2;(text in module2)




print "\t\t****************THE DIFFERENCES IN THE FILES ARE AS FOLLOWS****************\n\n\n";

printf "\t\t\t%-45s %s\n\n\n", $filename1, $filename2;

my $i = 0;
foreach (@codes1) {
    unless ($codes1[$i] eq $codes2[$i]) {
        
        printf "\t%-45s is not the same as %s\n\n", $codes1[$i], $codes2[$i];


    
    }
    
    
    
    $i++;
}

What's the output of your code?
For debugging purposes, please insert at line 20 following line:

printf ("i=%s, c1=%s, c2=%s\n", $i, $codes1[$i], $codes2[$i]);

Then show the output here.

The output is in the imagge i have uploaded.proble m is i have used dot as split parameter.so it is splittin 5.000
as 5 and oooo and taking it as two words and comparing.
and the result is not according .
the above code

module_from_1 contains module1.txt
module_from_2 contains module 2.txt

so i have to compare the both and print the differences as

module1 module2
parameter1 is not same as parameter2
so please try to help me

For i=1 to 58 all runs fine, there are no differences.
But it shows that at i=59 there is a difference. The problem is: why did the message inside the until()-condition, (see line 15) not print right before??? It must have been executed! Or have you modified it ? Or have you misspelled the variable name "codes1" and used a lowercase-el instead of a one character there? But then you should get a warning unless you have disabled it or also defined the misspelled variable before.

For debugging purposes, please run your program with 2 files that have only 3 lines each and where 1 is different!!! Then show the output here again.
Listing "millions" of lines here (and also without code tags) doesn't help much and only confuses.

By the way, all other lines are "different" because your algorithm doesn't recognise inserted or deleted lines. If you want to make a real diff, you should also compare with the "surroundin g" of the current line to find an offset point.

If you want to split by dot, but not inside a number, you must change your regular expression to use lookahead. So replace "\." with "\.(?!\d)". This means, split at a do only if the following character is not a number.

ya fine tanq for ur suggestion.i have to start tomorrow the thing u have said
