You can also uname -m

Sometimes the architecture name doesn't contain the bits information. Example: arch armv7l getconf LONG_BIT 32 So I prefer the getconf alternative.

Interesting. I've been using getconf LONG_BIT since I learned it here and if I don't know the arch at all which is rare, I run uname. I guess: uname -p outputs the processor info (what it is capable of), but uname -m outputs the OS info (what is actually installed)? The -m stands for machine, so I'm not sure.
