How to know you are running 32 or 64 bit Linux?
in console, type what command to know your OS bit?
|
Code:
anisha@linux-dpjj:~> uname -m -p -i |
mine is
Linux asus 2.6.35-22-generic #33-Ubuntu SMP Sun Sep 19 20:34:50 UTC 2010 i686 GN means what? 32 bit? |
any software like CPUZ for linux?
|
as far as i know:
to find if your processor is 64bit the command would be: cat /proc/cpuinfo|grep flags Quote:
and the command(s): Quote:

getconf LONG-BIT will return 32 for 32bit OS and 64 for 64bit OS. hope this help, |
64bit Ubuntu will make what differences?
|
64bit Linux in general (including ubuntu) will make most apps run faster, your hardware can see more than 4gb of ram (of course you can use pae kernel with 32bit), you are able to use 32 and 64 bits apps (long as you have 32 and 64 bit libraries), get the most out of your 64bit cpu and more ;)

All of the i#86 codes (such as your i686) mean 32 bit x86. Quote:

I have always installed 64-bit Linux when I had that choice (hardware and distribution support available). Maybe 64 bit is better, maybe it is worse (too hard for me to measure) but especially considering software trends into the future, the chance that 64bit is or will be a lot better outweighs the chance that it is a little worse. I generally do not advise anyone to change an existing 32bit install to 64bit, because I think that change is likely to be harder than installing Linux from scratch (because of all the settings and options etc. you've accumulated since installing). Choosing 64 bit instead of 32 bit when you're doing a full install anyway is a very inexpensive choice and reasonable to do based on only unsupported speculation that 64 bit might be better. Switching is harder and deserves a more informed choice. |
Dear Friends,
now I am running Ubuntu Ultimate 32 bit, but I have just got a 64bit ISO file, my CPU is 64bit, 32 bit is running well, but i never install 64 bit linux, I wish to try 64 bit, but many people it makes no significant difference you can "feel", so i am indecisive, do you think worth installing the 64bit Ubuntu? |
While I am a big fan of 64bit, I would tell you to use what you have installed. When you install the next time(new release, fubar something, etc) consider using 64bit. Doing large number crunching (video conversion, photo editing, etc) will show you a HUGE improvement in performance(using 64bit). Web browsing and similar stuff you really will not be able to tell the difference.

Hi,

32bit vs 64bit debate is moot. If 32 bit meets your needs then why change? Expected gain? Most applications are still 32bit. This said generally, you could install 64 bit Gnu/Linux with a multilib to take advantage of both. :hattip: |

Hi,
I'll bet that there are more 32 bit apps then 64bit for Gnu/Linux. :hattip: |
While that MAY be true, I would bet the ones that do not have a 64 bit version are pretty obscure. Virtually anything you can compile, can be compiled 64 bit.
