Re: [h-e-w] xargs fails with "grep: Invalid argument"

[egarrulo]

Thanks for answering. I've deleted the "-e" after "xargs" (because I
think the second one is passed to grep), but that didn't fix the
issue:


find . "(" -path "*/SCCS" -o -path "*/RCS" -o -path "*/CVS" -o -path
"*/MCVS" -o -path "*/.svn" -o -path "*/.git" -o -path "*/.hg" -o -path
"*/.bzr" -o -path "*/_MTN" -o -path "*/_darcs" -o -path "*/{arch}" ")"
-prune -o  -type f "(" -iname "*.el" ")" -print0 | xargs -0 grep -i -n
-e "redefined"
xargs: grep: Invalid argument

xargs' help for `-0' says it should look like `-0prtx', but I don'
understand what that means.

However, now I'm checking out `ack' (see betterthangrep.com) + ack.el
(see http://www.shellarchive.co.uk/content/emacs.html), which seems to
eat those big directories (only thing worse than grep is that output
is not incremental).
