Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

check if your processor is 32 or 64 bit

i686 = 32 bits

x86_64 = 64 bits

the command "getconf LONG_BIT" will work just as well.

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives

Know a better way?

If you can do better, submit your command here.

What others think

To check the processor for 64/32bit use: grep flags /proc/cpuinfo | grep lm

'arch' command is the shortest way to get this info

Comment by zolden 293 weeks and 2 days ago

x86_64 systems can run both 32-bit and 64-bit software. `uname` and `arch` show you the compiled arch of specifically the kernel software, but not the capabilites of the actual hardware.
