Fine. Then read that as "with libc doing the lookup", since execlvp() is just a libc wrapper around the kernel execve(). The point I was trying to get at was that I don't know if bash does all the PATH lookups itself, or if it delegates; and therefore, I don't know if EXECIGNORE can (or should) affect PATH lookups. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
