thanks Don
Roland got me access to a solaris 11 sun4
now the only difference is
VERSION synomym for POSIX_VERSION and _POSIX_VERSION
_POSIX2_SYMLINKS synomym for POSIX2_SYMLINKS
these are not that important (from my side anyway)
they are provided by the builtin but not the underlying getconf
I've attached the test/comparison script I've been using
let me know if it looks like anything is missing
it tests "_" prefix or not and standard (e.g. POSIX or XOPEN) prefix or not
this checks that the builtin getconf covers valid names (and prefix
permutations)
of /usr/bin/getconf names:
$SHELL testgetconf.sh getconf /ust/bin/getconf
the output for the latest (unposted) version is:
VERSION - "199506" DIAGNOSTICS
_POSIX2_SYMLINKS / "1" DIAGNOSTICS
this shows the differences between getconf and /usr/bin/getconf for the
union of names (and prefix permutations) of both (so it will include
non-standard builtin getconf extension names not provided by /usr/bin/getconf):
$SHELL testgetconf.sh --diff getconf /ust/bin/getconf
and this shows the differences between /usr/bin/getconf and
/usr/xpg4/bin/getconf:
$SHELL testgetconf.sh --diff /usr/bin/getconf /usr/xpg4/bin/getconf
note that the builtin getconf for posted ksh93s- will show many diffs
