Hi guys,

I'm trying to adjust the ISPConfig installer so that it also supports 64-bit systems. Now my question is: what would be the best way to test if the operating system (not the processor!) is a 64-bit Linux - please keep in mind that it is possible to install a 32-bit Linux on a 64-bit processor!

I think it is a good idea to use the

Code:

uname

command to find out about the operating system - but which switch do I use?

Code:

uname -m

prints the machine hardware name. On a 64-bit SuSE 10.0 this gives back

Quote:

x86_64

Code:

uname -p

prints the processor type. On a 64-bit SuSE this also bives back

Quote:

x86_64

.

The same commands issued on a 32-bit Debian Sarge show the following:

uname -m: i686

uame -p: unknown

So I guess uname -m would be the right command to find out about the operating system.

Do you have better suggestions?

Also, if you happen to run a 64-bit Linux (Fedora, Debian, SuSE, Mandriva, CentOS, ...), please post the output of both

Code:

uname -m

and

Code:

uname -p

here.
