Search for a particular line from a file and paste it in all the other files

[powerfulperl]

I have several files Log.100 Log.200,Log.300 .... which are in an array
Log.100 file contains the data
gpg RC (54321)
Testion option OK
Local=IN
AIX.SHA1.So

and Log.200 file and other files contains data
gpg RC (54321)
Testion option OK
Linux.SHA1.so
All files misses the line 'Local=IN' except Log.100. So I want to copy the line Local=IN and then paste it in all the remaining files after the line 'Testing option OK'.

Note:- When I read the files by an array, I am not sure which file i.e (Log.100, Log.200,or Log.300 I will be reading first)
All the Log files are in a one single directory.

My plan was to use grep command in the perl script and traverse each file through an array and whenever it finds that line copy and save it in a variable and again traverse all the files and paste the variable value after the line 'Testion Option OK' in all the files.
Kindly provide the code.
your help will be appreciated
Thanks

With what part of this problem are you having difficulty?
Please be specific.
Do you know how to get a list of file names?
Do you know how to open a file?
Do you know how to test a line of a file for a specific string?

Show your code, and you will get help on how to improve it.

I have this code with me, but I am looking at easy and sophisticated code. Well I want the code to be very understandable and easy.

use strict; 
use warnings; 
my @filenames => (dw log.100 log.200 log.300); 
foreach my $filename (@filenames) { 
    next if /\Afile\.100\Z/xms 
    eval { 
        open my $filehandle, '<', $filename or die Cannot open $filename; 
        open my $temphandle, '>', 'templog' or die Cannot open 'templog'; 
        foreach (<$filehandle>){ 
            print or die "error copying $filename"; 
            print 'Local=IN' or die "Error adding line" if /Testing Option OK/; 
        } 
        close $filehandle or die "error closing $filename"; 
        close $temphandle or die "error closing tempfile"; 
        unlink $filename or die "error deleteing original $filename"; 
        rename 'templog', $filename; 
    }; 
}

Kindly modify the code in a simple way, if possible.

[powerfulperl]

I can understand the above code but I want to write it in a different way so that it looks simple.

[toolic]

Your code does not compile. Please fix the syntax errors and post new code inside CODE tags which shows proper indentation.

[numberwhun]

I have added the code tags to your post. In the editor, there is a # symbol. If after you enter your code you highlight it, simply click the hash symbol and it will add the code tags for you.

Jeff

Check if this is ok

   1. use strict; 
   2. use warnings; 
   3. my @filenames =(log.100, log.200, log.300); 
   4. foreach my $filename (@filenames) { 
   5.     next if /\Afile\.100\Z/xms 
   6.     eval { 
   7.         open my $filehandle, '<', $filename; 
   8.         open my $temphandle, '>', 'templog'; 
   9.         foreach (<$filehandle>){ 
  10.             print or die "error copying $filename"; 
  11.             print 'Local=IN' or die "Error adding line" if /Testing Option OK/; 
  12.         } 
  13.         close $filehandle or die "error closing $filename"; 
  14.         close $temphandle or die "error closing tempfile"; 
  15.         unlink $filename or die "error deleteing original $filename"; 
  16.         rename 'templog', $filename; 
  17.     }; 
  18. }

This question has been cross posted in multiple forums and the one where this code was given can be found at http://perlguru.com/gforum.cgi?post=...=unread#unread

[RonB]

It appears to me that "powerfulpe rl" wants someone to write a custom and fully tested script rather than learning how.

My suggestion is to look/ask here http://rentacoder.com/cs/default.aspx

[powerfulperl]

Dude I know what I wanted, I have gone through the code but there seems to be problem with the existing code of mine. I just need a true programmer who can guide me in sorting out my problem rather than wasting time by giving other site links.

If you can help then plz assist me.

[RonB]

Bill, the person that gave you the code, is a good Perl programmer and I suspect he put in the few extremely minor errors to see if you knew Perl.

Lets start with this line, which has 3 errors. Can you find and fix one of them?

my @filenames => (dw log.100 log.200 log.300);

This line is easier, it has 1 problem. Can you find it?

next if /\Afile\.100\Z/xms
