Duplicate lines
Dear All,

I have a two-column data file and want to duplicate data in second column w.r.t. first column.

My file looks like:
Code:
2   5.672
1   3.593
3   8.260
...

And the desired format:
Code:
5.672
5.672
3.593
8.260
8.260
8.260
...

How may I do so please? I appreciate any help you may provide.
