Get System Information from the command line
Regardless of how many Mac’s you administer, there will surely come a time when you’ll need to retrieve relevant System Information. Gathering system information from the command line is vital for system and network administration, so the next time you’ve accessed a machine through SSH, find out what you need to know with two helpful command line tools. Here’s how, using the the sw_vers command and the system_profiler command:
sw_vers
The sw_vers command is short and sweet, it will give you the current operating system version and build number, with output as such:
$ sw_vers
ProductName: Mac OS X
ProductVersion: 10.4.9
BuildVersion: 8P2137
system_profiler
system_profiler is just a command line interface to the GUI app System Profiler (found in your Utilities folder). It’s very handy for learning about a machine over a network or remote connection via SSH. The standard output will blast you with screenfulls of content so it is best to pipe through the more command as follows:
$ system_profiler | more
This will allow you to view the output of system_profiler one screen at a time, navigable by the arrow keys and page up/down.
If you’re looking for information on your Airport connection, be sure to use the hidden Airport utility discussed here.
also you can use uname for unix related stats and information about your system
uname -a
it will spit back kernel info
/proc is a wondrous thing on ubuntu/debian (and more I’m sure) distros
cat /proc/cpuinfo for processor info
cat /proc/meminfo for RAM status
Jay’s tip is right but it doesn’t work on the Mac, is there a Mac OS X equivalent to the information in /proc ?
A little late of a response, but run this from the command line: sysctl -a | grep machdep.cpu

Buenas tardes… me gustaría saber como extraer la información de lo mismo pero de una copia que está en Time Machine. Tengo una copia de seguridad en Time Machine y me gustaría saber que disco duro tenía en ese momento y cual era su numero de serie. Muchas gracias!
Excuse me…:

I am converting a Python program from Linux to OSX. The current program iterates through all of the attached devices with the following
for f in glob.iglob(‘/sys/bus/usb/drivers/usb/*/product’):
Is there an equivalent directory to the /sys on OSX?
Thanks,

Take a look at the XML file at /System/Library/CoreServices/SystemVersion.plist
