[h-e-w] Global search/replace across files?

[Peter Davis]

I'm sure there must be a tool for searching and replacing based on regexps 
across files.  I just don't know what it is.  Can anyone enlighten me?

I'm trying to build nmh with cygwin, and the makefiles all contain

        SHELL = /bin/sh

For some reason, they only work if I change this to

        SHELL = sh

but there's a whole tree of makefiles that all contain this 
string.  (NOTE:  I can run 'sh', but for some reason, it doesn't run from 
the makefiles and I get an error.)

Thanks!
