Sure you don't want to -print0 | xargs -0? Except that 'find -print0' and 'xargs -0' are both GNU extensions, not available everywhere. We may be requiring gmake and gcc, but are we also requiring GNU find? The POSIX way to write this, without relying on extensions, is: find . -name '*.[od]' -exec rm -f {} + (although then you get into the arguments of whether 'find -exec {} +' is portable yet, even though it has now been required by POSIX for more than 4 years.) -- Eric Blake ebl...@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
