[X-Unix] Remove last ten lines of files

[Kuestner, Bjoern]

Hi David,

>It may look cryptic, but don't the other solutions look equally so?

They do. And I can just plug them in and hope they work as advertised or do
some guesswork should I need to modify them. 

I mean, there are books written about awk, perl, shell scripting etc. so to
understand each solution without explanation means digging deeper a lot into
awk etc., something that takes really long. 

In fact I (and probably not just me) would appreciate if those who posted
their solution would explain how they actually work. 

I hope that's not stretching things too far. This has not so much to do with
the original request but with understanding more.

Thanks in advance.

>done with the old simple apps like 'ed'.

Thanks for this one, too.

>Hence the name for grep when it was written.
