Sure, I could do that. I was hoping to be able to do it without faffing
around with the file. program | less is easier (especially if I've already
done it) than aborting less, rerunning progname | lc | less or even progname
| lc > file && less file for one search.

That would be affirmative on the fanboy bit. If I were talking about shell
programming I would have asked about grep. less is interactive. Never seen
or heard of perl used that way. Different tools, etc.
