Learn Today: How to Check Your Linux System with terminal: 32-bit or 64-bit?

If you need to know some basics about the operating system you’re running on your computer, without leaving a terminal, you are at the right address.

1. “uname” command, which prints system information to the screen. Open the terminal and run the command:

~$ uname –a

The you will see listing which shows whether your system is 32-bit (“i686” or “i386”) or 64-bit (“x86_64”).

2. The next command is more specific:

~$ uname –m

This displays only the machine hardware name and indicates, as above, whether your system is 32-bit (“i686” or “i386”) or 64-bit (“x86_64”).

3. The “arch” command is similar to the “uname -m” command and prints to the screen whether your system is 32-bit (“i686”) or 64-bit (“x86_64”)

~$ arch

If you would rather use a graphical tool to find out whether your system is 32-bit or 64-bit, you can use the “System Settings.”
