To identify if you are using 32 bit or 64 bit Linux OS, run command arch.

boby@sok-01:~$ arch
x86_64
boby@sok-01:~$

You can also use uname command

boby@sok-01:~$ uname -i
x86_64
boby@sok-01:~$

Another way is to use hostnamectl command and look for “Architecture”.

boby@sok-01:~$ hostnamectl
   Static hostname: sok-01
         Icon name: computer-desktop
           Chassis: desktop
        Machine ID: 70486772aac1410c9a8031851ab60a0d
           Boot ID: 46ff31881cca4e7090edb35f2af89a4a
  Operating System: Ubuntu 18.04.2 LTS
            Kernel: Linux 4.15.0-55-generic
      Architecture: x86-64
boby@sok-01:~$
