How to detect 386, amd64, arm, or arm64 OS architecture via shell/bash


bash shell arm posix x86-64 

uname -m

prints values such as x86_64, i686, arm, or aarch64.

bash shell arm posix x86-64

I suggest using:

dpkg --print-architecture

bash shell arm posix x86-64

I went with the following:

architecture=""case $(uname -m) in    i386)   architecture="386" ;;    i686)   architecture="386" ;;    x86_64) architecture="amd64" ;;    arm)    dpkg --print-architecture | grep -q "arm64" && architecture="arm64" || architecture="arm" ;;esac
