Hi list,
Can you look in to this?
[root@centos67 loop]# cat file1 firstname1 firstname2
[root@centos67 loop]# cat file2 lastname1 lastname2
I need a OUTPUT like this
*firstname1 lastname1firstname2 lastname2*
But I try the below command , i get below output. what is the real command to get the above output
[root@centos67 loop]# for line1 in $(cat file1 ); do for line2 in $(cat file2 ); do echo "$line1" "$line2";done;done; firstname1 lastname1 firstname1 lastname2 firstname2 lastname1 firstname2 lastname2
And also, I created a file3 like this
[root@centos67 loop]# cat file3 firstname1 lastname1 firstname2 lastname2
How can I get the same OUTPUT ?
*firstname1 lastname1firstname2 lastname2*
if I try below command, i get the below output.
[root@centos67 loop]# for i in $(cat file3);do echo $i;done; firstname1 lastname1 firstname2 lastname2
Could you pls help me to solve this ? THIS is very important to me.

An obvious solution is to use Perl. I suggest searching Stackoverflow for a solution using that language.
While checking, I discovered the paste program does just what you want. So try "man paste".

Assuming your files 1&2 will be longer than 2 lines, consider this:
paste -d' ' file1 file2 | awk '(NR%2) == 1 {l1 = $0; getline ; print l1 $0}'
