On a 64-bit system, 0xFFFFFFFF translates to 4,294,967,295, base 10 while 0xFFFFFFFFFFFFFFFF is the representation for -1). On a 32-bit system, -1 can be represented by the hex value 0xFFFFFFFF (which is 32 binary bits, all equalling 1). The signed integer equalling -1 is represented as the largest number that can be stored in a given number of bits for that architecture. Half of this set represents negative numbers and half represents positive numbers. A stable, proven foundation that’s versatile enough for rolling out new applications, virtualizing environments, and creating a more secure hybrid cloud. A 32-bit architecture only has 32 bits that it can use for storing signed integers while a 64-bit architecture has 64 bits! In other words the set of integers that can be stored is finite. The logic is very simple and it all boils down to how computers store signed integers. See my explanation below if you need to detect 8- 16- or some-other-bit architecture. It doesn't care if you're running ARM or not, and it should work on any system using bash or sh.īeware, this will assume the system is either 32-bit or 64-bit.

On a RHEL 8.3 system, these are the steps I followed to install and setup PostgreSQL. At the time I am writing this, the latest available version of PostgreSQL on my version of Red Hat Enterprise Linux (RHEL) is 12.5. If you're looking for a simple one-liner, this is the most reliable solution that I've found that returns 64 or 32. The latest available version of PostgreSQL is 13.2.
