File path in Go

In Go, you can get the file path using the filepath package which provides platform-independent file path manipulation. The Join() function of the filepath package is used to construct paths, and the Abs() function is used to get the absolute path of a file.

Here is an example of how to get the file path:

package main
import (

    "fmt"

    "path/filepath"

)
func main() {

    // Constructing a path using Join function

    path := filepath.Join("directory", "filename.txt")

    fmt.Println("File path is:", path)
// Getting the absolute path of the file

    fullPath, err := filepath.Abs(path)

    if err != nil {

        fmt.Println(err)

        return

    }

    fmt.Println("Absolute file path is:", fullPath)

}

In this example, we have used the Join() function of filepath package to construct the file path and pass two parameters: the directory name and the file name. Then we have used the Abs() function of the same package to get the absolute file path.

Note that the Abs() function returns an error in the case of a bad path, so you should always check for errors when using this function.
