Hi list,

Can you look in to this?


[root at centos67 loop]# cat file1
firstname1
firstname2

[root at 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 at 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 at 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 at 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.
