merge two files in one file
All,

I've basic knowlege on understanding UNIX Shell Programming. Right now I need to write a script for the following requirement. Kindly help me or suggest me how to write a Shell script.

I've 8 .csv files that are containing "Detail" records. Each file getting more than 1 million. Another eight files (.csv) are containing only one "Header" in each file. Now I want to MERGE these <Header> and <Detail> records in one file in the below format:

tstVenkat1.csv
This is Header Record
This is Detail Record
This is Detail Record
.
.
.
.
tstVenkat8.csv
This is Header Record
This is Detail Record
This is Detail Record

For <Header> record the file naming convention as tst1Venkat.xml and for <Detail> records the file naming convention as tstVenkat1.xml

From the above, want to send tst1Venkat.xml (ie., Detail records) to tstVenkat1.xml (ie., Header record containing here and it must be the first line in this file).

Kindly help to write in a shell script.

Thank you!

CPANPLUS::Shell(3pm)					 Perl Programmers Reference Guide				      CPANPLUS::Shell(3pm)

NAME

       CPANPLUS::Shell - base class for CPANPLUS shells

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

	   use CPANPLUS::Shell qw[Classic]  # load CPANPLUS::Shell::Classic;

	   my $ui      = CPANPLUS::Shell->new();
	   my $name    = $ui->which;	    # Find out what shell you loaded

	   $ui->shell;			    # run the ui shell

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.
