LINUX - how can I detect CPU architecture through terminal?

Hi - I have a machine on my network that I can only access through ssh, and I want to see if it'll support a 64-bit OS (currently running linux, but I don't know which). Any ideas how to accomplish this through terminal command/s? thanks.

• If you want to see the "bitnes" of the OS installed you can run this command.

  $ uname -m
  

  Regarding the actual capabilities of the processor you can always look the model up inside /proc.

  $ cat /proc/cpuinfo

• cat /proc/cpuinfo

  look for the 'lm' flag, it means 'long-mode' i.e. 64-bit capable.

  From Chopper3

• egrep '(vmx|svm)' --color=always /proc/cpuinfo
