Hi:

I was able to use the code below to rename my files and directories recursively from XXXD25573786-2k2XX to XXX75219XX.

But I was unable to update the data in these files in the same manner.

I spend two days trying but can't get it right. How can I expand or modify the code below to update the files. 

use File::Find;

my $old_hostname= "D25573786-2k2";
my $new_hostname = "75219";

finddepth (\&update_file , "C:\/elmPaul" );

sub update_file_dir 
{  
    if( /(.*)$old_hostname(.*)/i )# any files or directories
       {
           $orig = $File::Find::name ;
   $concat = $File::Find::dir . "\/$1$new_hostname$2";     rename($ori
+g, $concat) || print "error can't rename $orig to $concat: $!";
         }
     -f $_ && push (@files, "$File::Find::name");
} # end of sub update_file_dir

foreach $file (@files ) 
     {  
         open (IN,"$file");
         print "\nReading from file: $file \n";
         @lines = <IN>;
         close IN;
         
        foreach (@lines)
        {
         
         if ( /(.*?)$old_hostname(.*?)/i ) 
          { 
            s/(.*?)$old_hostname(.*?)/$1$new_hostname$2/sgi;
          }  
          
        open (OUT,">$file");
        print OUT @lines; 
       }
     }

If I ran the script the second time after the files and the directories had been renamed then it will update the files.

First time around the files and directories get rename and ONLY the file in "C:\elmPaul" get updated.

I also noticed that the script rename these files and directories from the bottom up. --kirk
