golang的build命令

下面命令会生成一个可执行文件realtime-chat

go build -o realtime-chat main.go rooms.go template.go

查看go build使用

go help build

The -o flag, only allowed when compiling a single package,
forces build to write the resulting executable or object
to the named output file, instead of the default behavior described
in the last two paragraphs.
