Hi;
With reference to the post below by Christopher L.Barnard and some of the answers that he received, I found out that `uname -p` on my sparc Solaris 8.0 machine is inconsistent with the results of both `isainfo *` and `psrinfo -v` commands.
`uname -p` tells that my machine is using a 32-bit ISA CPU type:
[fvsupprt@SON-TDI fvsupprt 16]$ uname -p
sparc
However, `isainfo *` tells that my machine is using a 64-bit CPU running 64-bit operating system:
[fvsupprt@SON-TDI fvsupprt 11]$ isainfo -bv
64-bit sparcv9 applications
[fvsupprt@SON-TDI fvsupprt 12]$ isainfo -nv
64-bit sparcv9 applications
[fvsupprt@SON-TDI fvsupprt 13]$ isainfo -kv
64-bit sparcv9 kernel modules
[fvsupprt@SON-TDI fvsupprt 14]$ isainfo -v
64-bit sparcv9 applications
32-bit sparc applications
[fvsupprt@SON-TDI fvsupprt 15]$ isainfo
sparcv9 sparc
`psrinfo -v` aggrees with `isainfo` command:
[fvsupprt@SON-TDI fvsupprt 17]$ psrinfo -v
Status of processor 0 as of: 05/16/06 10:42:03
Processor has been on-line since 04/17/06 11:40:07.
The sparcv9 processor operates at 400 MHz,
and has a sparcv9 floating point processor.
Status of processor 1 as of: 05/16/06 10:42:03
Processor has been on-line since 04/17/06 11:40:09.
The sparcv9 processor operates at 400 MHz,
and has a sparcv9 floating point processor.
Status of processor 2 as of: 05/16/06 10:42:03
Processor has been on-line since 04/17/06 11:40:09.
The sparcv9 processor operates at 400 MHz,
and has a sparcv9 floating point processor.
Status of processor 3 as of: 05/16/06 10:42:03
Processor has been on-line since 04/17/06 11:40:09.
The sparcv9 processor operates at 400 MHz,
and has a sparcv9 floating point processor.
[fvsupprt@SON-TDI fvsupprt 18]$
The answer in the post suggests that `uname -p` is the right command to use but it looks otherwise in my case here. Shouldn't `uname -p` return sparcv9 on my machine?
Any insight an enlightenment is appreciated.

TEH

Answers.
Don't forget "psrinfo -v" and "uname -p". Also the /usr/bin/sparc and
/usr/bin/i386pc binaries will return 0 on their respective CPU types.
Testing for the /usr/bin/i86 directory is definitely not a good idea
because it can be there on a sparc system as well. arch has been
depreciated and use of it is discouraged.
It looks like "uname -p" is the one to use.
