change it into a Perl script that iterates over the supplied arguments eg:
Code:
#!/usr/bin/perl
use strict;
use warnings;
for my $filename (@ARGV){
my $file_counter=0;
my $in_record=0;
open (my $file "<" $filename);
while($file){
s/\*/|/g;
s/~/\n/g;
if(/^ST/){
$in_record=1;
open (my $outfile, ">" , "$filename.$file_counter");
}
print $outfile $_ if $in_record;
if (/^SE/){
close $outfile;
$in_record=0;
$file_counter++;
}
}
close $file;
}
and call it with the list of files you wish to split as arguments

Hi there,
I need to split one huge file into separate files if the condition is fulfilled according to that the position between 97 and 98 matches with “IT” at the segment MAS. There is no delimiter file is fix-width with varous line length.
Could you please help me how I do split the file... (1 Reply)
All,
We receive a file with a large no of records (records can vary) and we have to split it into two files based on another file. e.g.
File1:

Hi All,
I have a rather stange set of requirements that I'm hoping someone here could help me with. We receive a file that is actually a concatenation of 4 files (don't believe this would change, but ideally the solution would handle n files).

Hi ,
I am having a scenario where I need to split the file based on two field values. The file is a fixed length file.

marc::batch
MARC::Batch(3pm) User Contributed Perl Documentation MARC::Batch(3pm)NAME
MARC::Batch - Perl module for handling files of MARC::Record objects
SYNOPSIS
MARC::Batch hides all the file handling of files of "MARC::Record"s. "MARC::Record" still does the file I/O, but "MARC::Batch" handles the
multiple-file aspects.
use MARC::Batch;
# If you have werid control fields...
use MARC::Field;
MARC::Field->allow_controlfield_tags('FMT', 'LDX');
my $batch = MARC::Batch->new( 'USMARC', @files );
while ( my $marc = $batch->next ) {
print $marc->subfield(245,"a"), "
";
}
EXPORT
None. Everything is a class method.
METHODS
new( $type, @files )
Create a "MARC::Batch" object that will process @files.
$type must be either "USMARC" or "MicroLIF". If you want to specify "MARC::File::USMARC" or "MARC::File::MicroLIF", that's OK, too.
"new()" returns a new MARC::Batch object.
@files can be a list of filenames:
my $batch = MARC::Batch->new( 'USMARC', 'file1.marc', 'file2.marc' );
Your @files may also contain filehandles. So if you've got a large file that's gzipped you can open a pipe to gzip and pass it in:
my $fh = IO::File->new( 'gunzip -c marc.dat.gz |' );
my $batch = MARC::Batch->new( 'USMARC', $fh );
And you can mix and match if you really want to:
my $batch = MARC::Batch->new( 'USMARC', $fh, 'file1.marc' );
next()
Read the next record from that batch, and return it as a MARC::Record object. If the current file is at EOF, close it and open the next
one. "next()" will return "undef" when there is no more data to be read from any batch files.
By default, "next()" also will return "undef" if an error is encountered while reading from the batch. If not checked for this can cause
your iteration to terminate prematurely. To alter this behavior, see "strict_off()". You can retrieve warning messages using the
"warnings()" method.
Optionally you can pass in a filter function as a subroutine reference if you are only interested in particular fields from the record.
This can boost performance.
strict_off()
If you would like "MARC::Batch" to continue after it has encountered what it believes to be bad MARC data then use this method to turn
strict OFF. A call to "strict_off()" always returns true(1).
"strict_off()" can be handy when you don't care about the quality of your MARC data, and just want to plow through it. For safety,
"MARC::Batch" strict is ON by default.
strict_on()
The opposite of "strict_off()", and the default state. You shouldn't have to use this method unless you've previously used "strict_off()",
and want it back on again. When strict is ON calls to next() will return undef when an error is encountered while reading MARC data.
strict_on() always returns true(1).
warnings()
Returns a list of warnings that have accumulated while processing a particular batch file. As a side effect the warning buffer will be
cleared.
my @warnings = $batch->warnings();
This method is also used internally to set warnings, so you probably don't want to be passing in anything as this will set warnings on your
batch object.
"warnings()" will return the empty list when there are no warnings.
warnings_off()
Turns off the default behavior of printing warnings to STDERR. However, even with warnings off the messages can still be retrieved using
the warnings() method if you wish to check for them.
"warnings_off()" always returns true(1).
warnings_on()
Turns on warnings so that diagnostic information is printed to STDERR. This is on by default so you shouldn't have to use it unless you've
previously turned off warnings using warnings_off().
warnings_on() always returns true(1).
filename()
Returns the currently open filename or "undef" if there is not currently a file open on this batch object.
