I have a 64-bit athelon processor running on my machine. How do I find
out if the installed OS is 64-bit or 32-bit Linux?

Thanks.

uname -a.


AMD64 is the generic tag name for a 64 bit kernel.

uname -m

There is a utility "Sysinfo" you should be able to find. At least Ubuntu 
9.10 software installer can find it.

If you look at the "GCC version" reported it should show something like 
"4.4.1 (i486-linux-gnu)," the "86" = 32bit.

Ask it

I think what you want is the output of the command "uname -m" which will
be i686 for 32-bit or x86_64 for 64-bit (or possibly amd64, not sure)

Whether you have a 32 or 64 bit kernel can be obtained with the uname
-m command. Note that you can run a 32 bit user land with a 64 bit
kernel, in which case uname -m will only tell you what kind of kernel
you're running.

There's a very similar discussion going on in
alt.os.linux.mandriva with some useful-looking script snippets.

Did somebody multi-post?

Doesn't look like it.  The thread in alt.os.linix.mandriva was
started by Dave Farrance, while this thread was started by
Kalyan.

Anyways, from that thread, I was surprised to find that uname -m
in a 32 bit install with a 64 bit cpu still returns i686, not
x86_64 as I expected.

To determine whether or not a 64 bit distro has been installed

if  [[ $(uname -m) == "x86_64" ]]; then
     echo "coreutils is 64 bit"
else
     echo "coreutils is 32 bit"
fi

if  [[ "$HOSTTYPE" == "x86_64" ]]; then
     echo "bash is 64 bit"
else
     echo "bash is 32 bit"
fi

if  [[ $(grep flags /proc/cpuinfo|grep -w lm) ]]; then
     echo "processor is 64 bit"
else
     echo "processor is 32 bit"
fi

While I suspect a 32 bit version of bash could be installed
on a 64 bit distro, I don't think a 32 bit version of coreutils
can be.

Which test should be used depends on what will be done based
on the type detected.

This is a 64 bit kernel with a very 32 bit userland.
