Hi Alex,<br>
<br>
You are very close there. <i>uname -a</i> (or <i>uname -m</i>)
will tell you if it's 32 or 64 bit and the bit at the end before
GNU/Linux is the indicator. However <i>i686</i> shows it is 32bit,
if it was 64bit it would have <i>x86_64</i>.<br>
<br>
Another command you can use is:<br>
<pre class="lang-sh prettyprint"><code><span class="pln">getconf LONG_BIT</span></code></pre>
(the answer being 32 or 64)<br>
<br>
It is possible to run 32bit Linux on a 64bit CPU. The above commands
will only tell you about the currently installed Linux not if the
processor will support 64bit.<br>
<br>
If you want to know about the physical processor instead of the
current operating system run:<br>
<pre>cat /proc/cpuinfo
</pre>
(if the list of 'flags' has <i>tm</i> it is a 32 bit processor, if
the flags have <i>lm</i> it's 64bit)<br>
<br>
Hope that helps.<br>
Cheers,<br>
Ross.<br>

How can you find out if an install is 32 or 64 bit?<br>
<br>
Hi folks. I've got an install of Ubuntu 1o.1o Maverick on my
laptop but don't remember if it's a 32 or 64 bit install. Is there
an easy way to find out?<br>
'uname -a' returns:<br>
Linux Anna 2.6.35-22-generic #33-Ubuntu SMP Sun Sep 19 20:34:50
UTC 2010 i686 GNU/Linux<br>
<br>
Am I correct in thinking that the i686 indicates it is a 64 bit
installation?<br>
Tia, from Alex.<br>
