Solaris 'prtdiag' Utility

Want to find out how much memory is on your machine, how many processors it has, how fast they are, and that sort of thing?

There's a handy little utility that will tell you all this and more, but it's tucked away in an obscure directory - you might never stumble across it. It's called prtdiag. Run it like this:

/usr/platform/sun4u/sbin/prtdiag -v | more

Here's what the output looks like on my machine:

System Configuration:  Sun Microsystems  sun4u Sun Ultra 60 UPA/PCI (2 X UltraSPARC-II 296MHz)
System clock frequency: 99 MHz
Memory size: 1280 Megabytes
