How will you see Linux bit ?

The machine hardware name lists whether your system is 32-bit (“i686” or “i386”) or 64-bit (“x86_64”). Notice that the processor type and hardware platform also indicates 32-bit or 64-bit.

To use the “uname” command to only find out whether your system is 32-bit or 64-bit, type the following command and press Enter.

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”).

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”). Type the following command and press Enter.

arch

You can also use the “file” command with a special argument (“/sbin/init”) to find out whether your system is 32-bit or 64-bit. Type the following command and press Enter.

file /sbin/init

The following output is printed to the screen. The text outlined in red indicates whether your system is 32-bit or 64-bit.

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.” Click the “System” menu button (gear button) in the upper-right corner of the screen and select “System Settings” from the drop-down menu.

On the “System Settings” dialog box, click “Details” in the “System” section, as shown below.

The “Details” screen displays. On the “Overview” screen, the “OS type” is listed as either “64-bit” or “32-bit,” along with other basic information about your Ubuntu system.
