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

Actually this code is suitable for 2 to 4 lines file. but what will happen when there is 100 and 1000 lines are there in the file?
