[tlug] shell question

[Stephen Lee <sl@example.com>]

Hi all,

I often find myself wanting to remove from piped data lines starting
with one regxp and ending with another.  e.g.

This is line 1
Beginning
some unneeded data
some more unneeded data
Finishing
Some more lines

I want to remove every line between 'Beginning' and 'Finishing'
inclusive.  Do you know any quick, short command that does it?

Stephen
