I have a file that I need to parse multiple sections from the file.

The file contains multiple lines that start with ST (Abunch of data)
Then the file contains multiple lines that start with SE (Abunch of data)

SE*30*0001
ST*810*0002

I need all of the lines between and including these.
They are invoices.
The invoice starts with the ST line and ends with the SE line.

I need to break out all of the invoices into separate files.

Can someone please help me. I know Grep, sed, or AWK can do this, but not sure how.
Thank you

It turns out that split magically solves your problem.

(Read "man split" for details.)
