1. I am trying to store this values in one variable like (temp = 84|589|60|5)
Because I have hundreds or thousands of lines and don't know how many enries are there. So I am planning to give seperator (|) to store values.
2. In both SunOS and Linux systeam
3. I am using
#!/bin/ksh
4. no tools directly in Linux and Sunos systeam
Thanks you
What are you going to do with this variable with hundreds of thousands of values separated by vertical bars in it once you get it? If you're going to process each value, you'd probably be much better off processing each value as you find it piped into a loop to process the values. Storing a set of values in a variable as a string that is about a quarter of a megabyte long and then processing that string doesn't seem like a good approach.
And, once more:
What have you tried so far? If you refuse to answer this question, it will likely take a lot longer to get a resolution to your problem. We're here to help you learn how to use Linux and UNIX tools; not to write your code for you. And even more importantly, if you show us what you've done, we might get a much better idea of what you're trying to do!

Mail::Mbox::MessageParser::Grep(3) User Contributed Perl Documentation Mail::Mbox::MessageParser::Grep(3)
NAME
Mail::Mbox::MessageParser::Grep - A GNU grep-based mbox folder reader
SYNOPSIS
#!/usr/bin/perl
use Mail::Mbox::MessageParser;
my $filename = 'mail/saved-mail';
my $filehandle = new FileHandle($filename);
my $folder_reader =
new Mail::Mbox::MessageParser( {
'file_name' => $filename,
'file_handle' => $filehandle,
'enable_grep' => 1,
} );
die $folder_reader unless ref $folder_reader;
# Any newlines or such before the start of the first email
my $prologue = $folder_reader->prologue;
print $prologue;
# This is the main loop. It's executed once for each email
while(!$folder_reader->end_of_file());
{
my $email = $folder_reader->read_next_email();
print $email;
}
DESCRIPTION
This module implements a GNU grep-based mbox folder reader. It can only be used when GNU grep is installed on the system. Users must not
instantiate this class directly--use Mail::Mbox::MessageParser instead. The base MessageParser module will automatically manage the use of
grep and non-grep implementations.
METHODS AND FUNCTIONS
The following methods and functions are specific to the Mail::Mbox::MessageParser::Grep package. For additional inherited ones, see the
Mail::Mbox::MessageParser documentation.
$ref = new( { 'file_name' => <mailbox file name>, 'file_handle' => <mailbox file handle> });
<file_name> - The full filename of the mailbox
<file_handle> - An opened file handle for the mailbox
The constructor for the class takes two parameters. The file_name parameter is the filename of the mailbox. The file_handle argument is
the opened file handle to the mailbox.
Returns a reference to a Mail::Mbox::MessageParser object, or a string describing the error.
