Linux System Information

Find if your Linux is 64 bit is by using:

$getconf LONG_BIT

`uname -m` tells only about the kernel, the userspace and distro can be still 32-bit. Similarly `lscpu` only tells what the CPU is capable of, not if OS, kernel and distro are 32 or 64 bit.
 

 

$file /lib/systemd/systemd

$lscpu

$uname -i

$uname -m 

$dpkg --print-architecture
