Insert a line grepping a file
Hi

I have a file name file1.txt & file2.txt which looks like below

file1.txt
Code:
Name=alan
Name=math
Name=don

file2.txt
Code:
afdsfsdf
asdfasdfsd
sdfsd
dsfas

Now I have to grep for all the names and insert a line in file2.txt for each name after line3 as follows

file2.txt
Code:
afdsfsdf
asdfasdfsd
Name=alan Type=customer
Name=math Type=customer
Name=don Type=customer
sdfsd
dsfas

Can you please give me command a onliner if possible to do this
thanks in advance

Tough to achieve using a one liner , hope this is the simplest way.
Code:
use strict;
use warnings;
use Data::Dumper ;

my @a = `cat f1.txt`;
my @b = `cat f2.txt`;
splice @b , 2, 0 ,@a ;
print @b ;

Try:

Code:
awk -F= 'NF==2{ A[$0]; } NF==1 && ++f ==2 { print; for (i in A)  print i,"Type=customer";;}f != 2&&NF==1' file1 file2
