To find out if your processor(s) is/are 32-bit or 64-bit, you can check the /proc/cpuinfo file.
If you have a 64-bit processor, you will see long mode (lm) in the flags section of /proc/cpuinfo.
cat /proc/cpuinfo | grep flags | grep ” lm ” | wc -l
If the result of the command above is 1 or more then you have a 64-bit processor. If the result is 0 then you have a 32-bit processor(s).
