I am downloading the 64 bit version, but the tar file is labeled amd64.tar.xz...will this work on mhy intel 64 system, or should I just use the 32bit version?
amd64 is equivalent to
x86_64, is the 64-bit version of the x86 instruction set. Intel called it Intel64 initially.
Different distros use different naming, a bit confusing but in fact they are the same thing. Debian uses
amd64 (that's why Ubuntu uses the same) while Fedora, Arch Linux use
x86_64. Don't worry;-)
