AFAIK it's more likely that you build ksh93 the normal way and not with
the adjusted builtin table which changes the builtin command bindings to
match PSARC 2006/550. If the list of default builtins is not adjusted
you may get a couple of weired effects (the same issue+bug in "uname"
builtin hit Blastwave's "pkg-get" badly) ...
I ran a diff over the log files, it looks that the 'set' builtin
behaves differently (old log is Bourne shell, new log is ksh93):
+ /usr/sbin/route -n add default -gateway 192.168.0.1
+ set -- add net default: gateway 192.168.0.1: entry exists
-+ [ 17 -ne 0 -a x192.168.0.1: = x192.168.0.1: ]
-do_delete=no
-+ [ -n 192.168.0.1 -a no = yes ]
-+ [ != true ]
++ [ 0 -ne 0 -a x192.168.0.1: = x192.168.0.1: ]
++ [ -n 192.168.0.1 -a yes = yes ]
++ /usr/sbin/route -n delete default -gateway 192.168.0.1
++ 1> /dev/null
++ [ '' != true ]
+ [ -z 192.168.0.1 ]
The sh manual page is ambiguous which return code is expected for
'set'. Is there any other documentation for sh?
