Hi,<br />
<br />
I have few files like this:<br />
file1:<br />
22 110.1 <br />
33 331.5 22.7 <br />
5 271.9 17.2 33.4<br />
4 55.1 <br />
<br />
file1 has total 4 column but some of them are missing in few row.<br />
<br />
file2:<br />
5 H<br />
22 0<br />
<br />
file3:<br />
4 T<br />
5 B<br />
22 C<br />
121 S<br />
<br />
in all these files first column is the main source of matching their entries. So What I want in the output is only those entries which is coming in all three files.<br />
output required:<br />
5 271.9 17.2 33.4 5 H 5 T<br />
22 110.1 22 0 22 C<br />
<br />
