How to detect 386, amd64, arm, or arm64 OS architecture via shell/bash
提问by Justin
I'm looking for a POSIX shell/bash command to determine if the OS architecture is 386, amd64, arm, or arm64?

uname -m
prints values such as x86_64, i686, arm, or aarch64.
打印值，例如x86_64，i686，arm，或aarch64。

I went with the following:
我采用了以下方法：
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
