Hi Gurus,
I have a file say for ex. file1 which has 3500 lines in it which are different account numbers and another file (file2) which has 230000 lines in it. I want to read all the lines in file1 and delete all those lines from file2 which has that same pattern as in file1. I am not quite... (4 Replies)

What I have is a file which has contents like this:

autosplit
AutoSplit(3pm) Perl Programmers Reference Guide AutoSplit(3pm)NAME
AutoSplit - split a package for autoloading
SYNOPSIS
autosplit($file, $dir, $keep, $check, $modtime);
autosplit_lib_modules(@modules);
DESCRIPTION
This function will split up your program into files that the AutoLoader module can handle. It is used by both the standard perl libraries
and by the MakeMaker utility, to automatically configure libraries for autoloading.
The "autosplit" interface splits the specified file into a hierarchy rooted at the directory $dir. It creates directories as needed to
reflect class hierarchy, and creates the file autosplit.ix. This file acts as both forward declaration of all package routines, and as
timestamp for the last update of the hierarchy.
The remaining three arguments to "autosplit" govern other options to the autosplitter.
$keep
If the third argument, $keep, is false, then any pre-existing "*.al" files in the autoload directory are removed if they are no longer
part of the module (obsoleted functions). $keep defaults to 0.
$check
The fourth argument, $check, instructs "autosplit" to check the module currently being split to ensure that it includes a "use" specifi-
cation for the AutoLoader module, and skips the module if AutoLoader is not detected. $check defaults to 1.
$modtime
Lastly, the $modtime argument specifies that "autosplit" is to check the modification time of the module against that of the
"autosplit.ix" file, and only split the module if it is newer. $modtime defaults to 1.
Typical use of AutoSplit in the perl MakeMaker utility is via the command-line with:
perl -e 'use AutoSplit; autosplit($ARGV[0], $ARGV[1], 0, 1, 1)'
Defined as a Make macro, it is invoked with file and directory arguments; "autosplit" will split the specified file into the specified
directory and delete obsolete ".al" files, after checking first that the module does use the AutoLoader, and ensuring that the module is
not already currently split in its current form (the modtime test).
The "autosplit_lib_modules" form is used in the building of perl. It takes as input a list of files (modules) that are assumed to reside in
a directory lib relative to the current directory. Each file is sent to the autosplitter one at a time, to be split into the directory
lib/auto.
In both usages of the autosplitter, only subroutines defined following the perl __END__ token are split out into separate files. Some rou-
tines may be placed prior to this marker to force their immediate loading and parsing.
Multiple packages
As of version 1.01 of the AutoSplit module it is possible to have multiple packages within a single file. Both of the following cases are
supported:
package NAME;
__END__
sub AAA { ... }
package NAME::option1;
sub BBB { ... }
package NAME::option2;
sub BBB { ... }
package NAME;
__END__
sub AAA { ... }
sub NAME::option1::BBB { ... }
sub NAME::option2::BBB { ... }
DIAGNOSTICS
"AutoSplit" will inform the user if it is necessary to create the top-level directory specified in the invocation. It is preferred that the
script or installation process that invokes "AutoSplit" have created the full directory path ahead of time. This warning may indicate that
the module is being split into an incorrect path.
"AutoSplit" will warn the user of all subroutines whose name causes potential file naming conflicts on machines with drastically limited (8
characters or less) file name length. Since the subroutine name is used as the file name, these warnings can aid in portability to such
systems.
Warnings are issued and the file skipped if "AutoSplit" cannot locate either the __END__ marker or a "package Name;"-style specification.
"AutoSplit" will also emit general diagnostics for inability to create directories or files.
