Consider - we gave you a solution (with touch and -newer) that works now (and complies with POSIX), vs. the delay of waiting for adding a new extension feature and percolating it into your distro (probably a process of a couple of years, even if we do decide to enhance find, and even then, limits you to GNU find instead of POSIX). It's hard to justify adding a new feature if existing standard features already work without too much additional effort. However, you are correct that we can add suffix parsing to -mtime without violating POSIX, so it might make a nice syntactic sugar addition. If you are willing to write the patch, including documentation and testsuite additions, your proposal will get a lot further. But for now, it appears that no one else is interested in implementing it on your behalf. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
