Go Getting started with Go Listing Go Environment Variables
Example
Environment variables that affect the go tool can be viewed via the go env [var ...] command:
$ go env
GOARCH="amd64"
GOBIN="/home/yourname/bin"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/yourname"
GORACE=""
GOROOT="/usr/lib/go"
GOTOOLDIR="/usr/lib/go/pkg/tool/linux_amd64"
CC="gcc"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build059426571=/tmp/go-build -gno-record-gcc-switches"
CXX="g++"
CGO_ENABLED="1"
By default it prints the list as a shell script; however, if one or more variable names are given as arguments, it prints the value of each named variable.
$go env GOOS GOPATH
linux
/home/yourname
