System specification checking

Hi,

anybody know how to check the system specification for the unix by using the command like the memory size, cpu's speed and etc.

Thanks.

In Solaris, "prtconf" command will give you some information about your hardware.
Regards.

If you have /proc then
$ cat /proc/cpuinfo
$ cat /proc/meminfo

The command you are looking for is prtdiag.
It's in /usr/sbin in Solaris 10, or /usr/platform/<platform>/sbin in 9 and down. (may be in /usr/sbin in 9 also, but I don't remember off hand)
