The command "godoc ${fmt}" is used to access the documentation for the "fmt" package in Go.

GoDoc is a tool provided by the Go programming language that generates documentation for Go packages. It extracts documentation from Go source files and presents it in a web page format. The "godoc" command followed by a package name or import path allows you to access the documentation for that specific package.

In this case, "${fmt}" may be a placeholder for the actual import path of the "fmt" package. The dollar sign "$" is often used in Unix-like shells as a variable prefix. So, if you replace "${fmt}" with the actual import path, the command becomes "godoc fmt" which will display the documentation for the "fmt" package.
