Hi!
----
While looking for incompatibilities between Solaris commands and ksh93's
builtin commands I found a difference in the output of "uname -a"
The difference looks like this:
-- snip --
# use native Solaris "uname"
$ /usr/bin/uname -a
SunOS s10test001 5.10 Generic_118844-26 i86pc i386 i86pc
$ builtin | fgrep uname
/bin/uname
# use ksh93 builtin "uname"
$ export PATH=/bin:$PATH
$ uname -a
SunOS s10test001 5.10 Generic_118844-26 i86pc
-- snip --
Neither /usr/xpg4/bin/ nor /usr/xpg6/bin/ contain a "uname" variant so I
assume there is no standard, right ?
The builtin "uname" results the following help:
-- snip --
uname --help
Usage: uname [ options ]
OPTIONS
-a, --all Equivalent to -snrvm.
-d, --domain The domain name returned by getdomainname(2).
-f, --list List all sysinfo(2) names and values, one per line.
-h, --host-id|id
The host id in hex.
-i, --implementation|platform
The hardware implementation (platform); this is
--host-id on some systems.
-m, --machine The name of the hardware type the system is running
on.
-n, --nodename The hostname or nodename.
-p, --processor The name of the processor instruction set
architecture.
-r, --release The release level of the operating system
implementation.
-s, --os|system|sysname
The operating system name. This is the default.
-v, --version The operating system implementation version level.
-A, --everything
Equivalent to -snrvmphCdtbiRX.
-R, --extended-release
The extended release name.
-S, --sethost=name
Set the hostname or nodename to name. No output is
written to standard output.
-- snip --
Calling the Solaris /usr/bin/uname command with the "-snrvm" option
listed in the builtin commands help returns the same output then:
-- snip --
% /usr/bin/uname -snrvm
SunOS s10test001 5.10 Generic_118844-26 i86pc
-- snip --
Based on that it simply seems that the Solaris command's "-a" option is
the equivalent to "uname -snrvmpi":
-- snip --
% /usr/bin/uname -snrvmpi
SunOS s10test001 5.10 Generic_118844-26 i86pc i386 i86pc
% /usr/bin/uname -a
SunOS s10test001 5.10 Generic_118844-26 i86pc i386 i86pc
% uname -snrvmpi
SunOS s10test001 5.10 Generic_118844-26 i86pc i386 i86pc
-- snip --
David/Glenn:
I have attached a patch
("ksh93_solaris_uname_all_output_fix001.diff.txt") which syncs the
output of the ksh93 builtin command with the Solaris version in
/usr/bin/ - is that change Ok for you ?

Bye,
Roland
