How to check if a file path is absolute or relative using the path package in Golang?

To check if a file path is absolute or relative using the path package in Golang, you can use the IsAbs() function.

Here's an example:

package main

import (
    "fmt"
    "path/filepath"
)

func main() {
    filePath1 := "/path/to/file.txt"
    filePath2 := "relative/path/to/file.txt"

    isAbsolute1 := filepath.IsAbs(filePath1)
    isAbsolute2 := filepath.IsAbs(filePath2)

    fmt.Printf("%s is absolute: %v\n", filePath1, isAbsolute1)
    fmt.Printf("%s is absolute: %v\n", filePath2, isAbsolute2)
}

In the above example, the IsAbs() function from the path/filepath package is used to check if filePath1 and filePath2 are absolute file paths or not. The function returns a boolean value indicating whether the path is absolute (true) or not (false).

Running the above code will yield the following output:

/path/to/file.txt is absolute: true
relative/path/to/file.txt is absolute: false

As you can see, the first file path is considered absolute because it starts with a forward slash (/), while the second file path is considered relative as it does not start with a forward slash.
