In order to determine whether or not I have a 64bit OS installed, I have tried the following commands. The output of the commands do not tell me immediately if its a 32bit or 64bit OS.
After looking it up, I know armv7 is a 32 bit architecture. But is there a command that can give an immediate response?
$ uname -m armv7l
$ uname -a Linux raspberrypi 5.10.11-v7l+ #1399 SMP Thu Jan 28 12:09:48 GMT 2021 armv7l GNU/Linux
$ arch armv7l
$ dpkg --print-architecture armhf
