How to Use go doc and godoc for Documentation

Use go doc to view documentation for packages, symbols, or files directly in your terminal. Run go doc followed by the import path or symbol name to retrieve the associated comments and usage information.

go doc net/http

For a specific function within a package, append the symbol name to the path:

go doc net/http.Get

To view documentation for a local file without importing it, pass the file path directly:

go doc ./my_package.go

The go doc command is a built-in tool that lets you read the documentation comments written by developers directly in your terminal. It works like a quick reference manual for your code, showing you how to use functions, types, and packages without needing to open a web browser. You use it whenever you need to understand what a specific piece of Go code does or how to call it.
