Shell Programming and Scripting

hi,
I'd like to ask you if you can help me with such surely easy thing - I have some data and need to plot them. I have txt of data in two columns, tab separated, but some second columns are empty. like

Code:

1````       2
1.2`` 
3````       2
4.44` 
5`````
6.1```1

how can I erase all the lines with the second empty column? (2nd, 4th, 5th) The lenght of numbers in the first column varies.
the second column is initiated by tab despite its emptyness.
thank you!

If you want a quick and dirty solution, given your sample input,
I would run something like this:

Code:

awk 'NF > 1' infile

If it doesn't work with your real input file,
give us a bigger and more representative sample.

it works great!
thank you!
