Thanks for the reply but I not getting the o/p I want.

I think i had missed when I asked. In file1 i have no's 1111,2222,3333 in one column and in file 2 i have the same no's 1111,2222,3333 and each 1111,2222,3333 have some value next to it.

I need a to add the values in file 2 to file 1 if 1111,2222,3333 are there in file2
my file final o/p should be some what like this

file1
1. aa 1111
2. bbb 2222
3. ccc 3333
file2
1111 "this is a test file "
2222 "you are in File 2"
3333 " this is my o/p file"

MY output file should be in the following format
cat o/p
1. aaa 1111 "This is the file"
2. bbb 2222 " you are in file 2"
3. ccc 3333 " this is my o/p"

Thanks in advance.
