[gentoo-user] [OT] Use of sed

[Peter Humphrey]

Hello list,

I'm reduced to asking a newcomer's question: how can I make sed recurse down 
a directory tree? And while I'm at it, how do I change the field separator 
from / to enable me to search on that character?

I used to have a "SED and AWK" book, but it seems to have walked; and I 
can't see anything helpful from a Google search.
