I got your requirement differently, as it is not explicitly told !!

If at all you want both the files to be sorted based up on the first column and displayed, then use the following.

Code:
sort -k 1 file1 file2

"-k 1" is not really necessary as far as I can tell

Yes !! As far as it is first field it is not needed.

But that is a generic way i use, that is whichever field i would want to sort based upon i will give that NUMBER.

Anyway thanks for pointing it out.

Thanks for your reply. I don't need to sort the file.
I just want the out file should have first line from file1 and 2nd line from 2nd file and 3rd line from first file and 4th line from second file. i.e. in output file, all odd numbered lines are from first file and all even numbered lines are from second file.

Dear friend,

You use the following way also to add the file content. Using the head and tail you can get the result.

file content
a 123 aqsw
c 234 sfdr

file1 content
b 345 hgy
d 4653 jgut

In the following coding "out" is the new file,which contain the content of the above two files. what you need
Code:
 
head -n 1 file > out 
head -n 1 file1 >> out  
tail -n 1 file >> out 
tail -n 1 file1 >> out

out content
a 123 aqsw
b 345 hgy
c 234 sfdr
d 4653 jgut
