Can anyone explain why I am getting two different version strings based on whether GOROOT it set versus when called within a package?

bash $ /usr/local/go/bin/go version go version go1.26.2 linux/amd64 $ md5sum /usr/local/go/bin/go 7d6b0bfc432317c28eca07c22d4ab193 /usr/local/go/bin/go $ $GOROOT/go version bash: /go: No such file or directory $ export GOROOT=/usr/local/go/bin/ $ md5sum $GOROOT/go 7d6b0bfc432317c28eca07c22d4ab193 /usr/local/go/bin//go $ $GOROOT/go version go version go1.25.5 linux/amd64
