I have a large text file (humongous.txt) with the following structure

date 1-2-2005

line4
date 1-3-2005
line5
line6

Is there any tool which will split the above file and give me three smaller files 1-1-2005.txt, 1-2-2005.txt, 1-3-2005.txt etc., where

1-1-2005.txt will be

date 1-1-2005
line1
line2

1-2-2005.txt will be

date 1-2-2005
line3
line4

1-3-2005.txt will be
line5
line6
line7
line8


There is absolutely no correlation between the date and the number of lines that it might contain. I just chose 3 dates, But in my file there are about 1000 such sections and I do not want to do it manually. I am wondering if there is any tool out there which does the above job.

I can do it with c or fortran but that does not appear to be elegant.

I looked at split, csplit. But they dont seem to do this. Googling did not help much. Any other ideas?

I can't think of any CL tools that would do this just for you, but it would be trivial to write a Java program to do this.
