Code:
$ cat test.file
123andsomeothervalues with a space at position 22
Not 123 but with the  space
123 but no spacein the appropriate column

$ perl -npi.bak -e 's/^(123.{18}) /$1X/' test.file

$ cat test.file
123andsomeothervaluesXwith a space at position 22
Not 123 but with the  space
123 but no spacein the appropriate column

If the space is in position 800, then there a 799 characters before it not 800 so the quantifier should be 796 ie:
Code:
perl -npi.bak -e ' s/(123.{796}) /${1}X/' infile

Perhaps my ability to count was compromised by a dangerous caffeine deficiency, currently remedying this cU.

::Application::Plugin::Authentication::Driver::GeneriUsermContributed Perl DocumeCGI::Application::Plugin::Authentication::Driver::Generic(3pm) NAME
CGI::Application::Plugin::Authentication::Driver::Generic - Generic Authentication driver VERSION
This document describes CGI::Application::Plugin::Authentication::Driver::Generic version 0.20 SYNOPSIS
use base qw(CGI::Application); use CGI::Application::Plugin::Authentication; __PACKAGE__->authen->config( DRIVER => [ 'Generic', { user1 => '123', user2 => '123' } ], ); DESCRIPTION
This Driver offers a simple way to provide a user database to the CGI::Application::Plugin::Authentication plugin. It offers three ways to provide a list of users to the plugin by providing a hash of username/password pairs, an array of arrays containing the username and password pairs, or a code reference that returns back the username, or undef on success or failure. EXAMPLE
my %users = ( user1 => '123', user2 => '123', ); __PACKAGE__->authen->config( DRIVER => [ 'Generic', \%users ], ); - or - my @users = ( ['example.com', 'user1', '123'], ['example.com', 'user2', '123'], ['foobar.com', 'user1', '123'], ); __PACKAGE__->authen->config( DRIVER => [ 'Generic', @users ], CREDENTIALS => [ 'authen_domain', 'authen_username', 'authen_password' ] ); - or - sub check_password { my @credentials = @_; if ($credentials[0] eq 'test' && $credentials[1] eq 'secret') { return 'testuser'; } return; } __PACKAGE__->authen->config( DRIVER => [ 'Generic', &check_password ], ); METHODS
verify_credentials This method will test the provided credentials against either the hash ref, array ref or code ref that the driver was configured with. SEE ALSO
