But bash 2.05a would dump core on 'unset NOT_SET', as documented in the autoconf manual. So the portable workaround that should keep NetBSD's sh -e happy is: foo=; unset foo if you aren't sure in advance whether foo is set. $ /bin/sh -ce 'unset foo; echo hi' $ /bin/sh -ce 'foo=; unset foo; echo hi' hi -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
