filepath.Abs() Function in Golang With Examples

In Go language, path package used for paths separated by forwarding slashes, such as the paths in URLs. The filepath.Abs() function in Go language used to return an absolute representation of the specified path. If the path is not absolute it will be joined with the current working directory to turn it into an absolute path. Moreover, this function is defined under the path package. Here, you need to import the “path/filepath” package in order to use these functions.

Syntax:

func Abs(path string) (string, error)

Here, ‘path’ is the specified path.

Return Value: It return an absolute representation of the specified path.

Example 1:

// Golang program to illustrate the usage of
// filepath.Abs() function

// Including the main package
package main

// Importing fmt and path/filepath
import (
    "fmt"
    "path/filepath"
)

// Calling main
func main() {

    // Calling the Abs() function to get
    // absolute representation of the specified path
    fmt.Println(filepath.Abs("/home/gfg"))
    fmt.Println(filepath.Abs(".gfg"))
    fmt.Println(filepath.Abs("/gfg"))
    fmt.Println(filepath.Abs(":gfg"))
}

Output:

/home/gfg <nil>
/.gfg <nil>
/gfg <nil>
/:gfg <nil>

Example 2:

// Golang program to illustrate the usage of
// filepath.Abs() function

// Including the main package
package main

// Importing fmt and path/filepath
import (
    "fmt"
    "path/filepath"
)

// Calling main
func main() {

    // Calling the Abs() function to get
    // absolute representation of the specified path
    fmt.Println(filepath.Abs("/"))
    fmt.Println(filepath.Abs("."))
    fmt.Println(filepath.Abs(":"))
    fmt.Println(filepath.Abs("/."))
    fmt.Println(filepath.Abs("//"))
    fmt.Println(filepath.Abs(":/"))
}

Output:

/ <nil>
/ <nil>
/: <nil>
/ <nil>
/ <nil>
/: <nil>
