merge two tab delimited file with exact same number of rows in unix/linux
Hi
I have two tab delimited file with different number of columns but same number of rows. I need to combine these two files in such a way that row 1 in file 2 comes adjacent to row 1 in file 1.
For example:
The content of file1:
field1 field2 field3
a1 a2 a3
b1 b2 b3
c1 c2 c3
File 2 contents:
field4 field5 field6 field7
d4 d5 d6 d7
e4 e5 e6 e7
f4 f5 f6 f7
After combining these two files becomes (again a tab delimited file):
field1 field2 field3 field4 field5 field6 field7
a1 a2 a3 d4 d5 d6 d7
b1 b2 b3 e4 e5 e6 e7
c1 c2 c3 f4 f5 f6 f7
Thanks for your help.
Mary
