envcmd

var CmdEnv = &base.Command{ UsageLine: "go env [-json] [-changed] [-u] [-w] [var ...]",	Short: "print Go environment information",	Long: ` Env prints Go environment information. By default env prints information as a shell script (on Windows, a batch file). If one or more variable names is given as arguments, env prints the value of each named variable on its own line. The -json flag prints the environment in JSON format instead of as a shell script. The -u flag requires one or more arguments and unsets the default setting for the named environment variables, if one has been set with 'go env -w'. The -w flag requires one or more arguments of the form NAME=VALUE and changes the default settings of the named environment variables to the given values. The -changed flag prints only those settings whose effective value differs from the default value that would be obtained in an empty environment with no prior uses of the -w flag. For more about environment variables, see 'go help environment'.	`, }
