In the Go programming language, to get the absolute path from a relative path – we use the Abs() function of path/filepath package. The Abs() function returns an absolute representation of the path. If the given path is not absolute it will be joined with the current working directory to turn it into an absolute path. The absolute pathname for a given file is not guaranteed to be unique.
