HI
I need to concatenate two files which are having headers. the result file should contain only the header from first file only and the header in second file have to be skipped.

file1:
name age
sriram 23

file2
name age
prabu 25

result file should be
name age
sriram 23
prabu 25

how to do this in script?

Thank in advance
Sriram

The following example assumes that the input files are all in the format of "file*"

#! /usr/bin/bash

ls file* >my_list
rm big_file 2>/dev/null
first_f=1

while read zf
   do
   if [ $first_f -gt 0 ]
      then
         cat "$zf" >>big_file
         first_f=0
      else
         tail +2 "$zf" >>big_file
   fi
done <my_list

exit 0
5 
 sed q file1 > file.new;ls file[12] | xargs -i tail +2 {} >> file.new

format head=
name 	age
---------------
.
format content=
@<<<<<<<@>>>>>>
$name $age
.
open(FH,">out.txt") or die "Can not open file!";
select FH;
$^=head;
$~=content;
open(FH1,"<first.txt");
while(<FH1>){
	if($.>1)
	{
		($name,$age)=split(" ",$_);
		write;
	}
	
}
close(FH1);
open(FH1,"<second.txt");
while(<FH1>){
	if($.>1)
	{
		($name,$age)=split(" ",$_);
		write;
	}
}
close(FH1);

you can use
cat file2>>file1
it append file2 after file1.
