How to Check if Raspberry Pi Operating System is 32-bit or 64-bit

To determine whether your Raspberry Pi is running a 32-bit or 64-bit operating system, you can use various methods. Here are some steps:

1. Using the Command Line (Terminal):

Open the Terminal and enter the following command:

uname -m

If it displays armv7l, it’s a 32-bit system; if it shows aarch64, it’s a 64-bit system.

2. View the contents of the /proc/cpuinfo file by entering the following command:

cat /proc/cpuinfo

Look for the model name or Features section. If it includes aarch64, it’s a 64-bit system.

3. Using the lscpu Tool:

Install the lscpu tool (if not already installed) and run:

sudo apt-get install lscpu
lscpu

Check the “Architecture” field in the output. If it shows aarch64, it’s a 64-bit system.

4. Using the dpkg Tool:

dpkg --print-architecture

If it shows armhf, it’s a 32-bit system; if it shows arm64, it’s a 64-bit system.

Choose any of these methods to determine whether your Raspberry Pi’s operating system is 32-bit or 64-bit.
