You just do this to wind people up, don't you?! OK, I'll take the
bait...

Ed scripts are a perfect way to edit files in-place,
programmatically. Awk and sed are basically stream editors, and
perl is most comfortable in this mode too.

However, I seem to have shot myself in the foot since I admit,
this script of mine ain't editing a file...

Just out of interest, how does one delete the first line in a sed
script? Damn thing always takes me a good 30 secs to fathom what
it does every time I look at it. And yes, I wrote it!

Cheerio,
