UNIX for Dummies Questions & Answers

Folks;
Is there a command to know if my hardware can run 64-bit or 32-bit?
I'm trying to re-install SUSE 64-bit on one of our server but i'm not sure if this server hardware designed for 32-bit only or for both

Any help?

cat /proc/cpuinfo (in case of ambiguosity look for cpu specs on vendor site/wikipedia)

Thanks, i see the file "/proc/cpuinfo" but i'm not sure how can i tell if the system hardware is 32 or 64-bit.
Could you please give me any hint about the contents of /proc/cpuinfo?

arch

uname -m

uname -a

all will give you the architecture.

Thanks. I know these commands, but i thought these gives you the OS that installed not the server architecture

i) What don't you understand?
ii) In my eyes "in case of ambiguosity look for cpu specs on vendor site/wikipedia" is not so ambiguos in itself.
iii) In case you really aren't up to find out your CPU from /proc/cpuinfo and google for its abilities post your /proc/cpuinfo here.

Below is what i see in my cpuinfo file & I'm not sure how to tell if my hardware architecture is 32-bit or 64-bit:
