in reply to How do I remove blank lines from text files?

I realize that I might be chastised for this, but
I feel the need to mention that this is a trivial
task for vi.

Type : and then issue this command 

%g/^$/d

[download]
The percent sign tells vi 'do this for all lines in the
file.' The g operator means 'globally', and the
d operator means 'perform deletion on the lines
that match'.

    Of course, if you're going to bother to start up vi, you might as well just do perl -pi -e 's/^\n$//' file.txt But I think this exceeds the scope of the original poster's question, since his program is already parsing the file.
