8 points
In this short article, we would like to show how to check used machine architecture (Intel/AMD, x86/x64, 32bit/64bit) under Bash.
⚠️ Warning ⚠️: this solution works only for x86/x64 processors.
Quick solution:

case "$(uname -m)" in4
amd64) echo '64bit' ;;5
x86_64) echo '64bit' ;;6
i686-64) echo '64bit' ;;7
x86) echo '32bit' ;;8
x86pc) echo '32bit' ;;9
i386) echo '32bit' ;;10
i686) echo '32bit' ;;11
i686-AT386) echo '32bit' ;;12
# ...13
# Add other cases here ...14
# ...15
*) echo 'unknown' ;;16
esac
arch command prints machine hardware name same as uname -m command.
