Rather, the 'test' binary and the 'lbracket' binary differ in one crucial aspect: 'lbracket' requires its last argument in argv[] to be "]". It is not ksh, but lbracket itself that requires the matching ], and it is this fact that allows us to obey POSIX while still allowing '[ --help' to produce help text, even though 'test --help' cannot do so (that is, '[' has an escape hatch that 'test' does not). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
