How to tell if Linux is 32 or 64 bit
Sometimes you want to tell if your Linux installation is 32 bit or 64 bit.
Short story:
just type this:
getconf LONG_BIT
Longer story:
You can also type
uname –m
if it is x86_64, then it is 64bit.
cat /proc/cpuinfo doesn’t work in this case, because what it shows is about CPU. 32bit linux can run on 64bit CPU.
They should make this more obvious.
