Golang : Match strings by wildcard patterns with filepath.Match() function

Problem:

You want to match strings using the same wildcard patterns commonly used in Linux/Unix shells such as *.go or *data[0-9]*. How to do that?

Solution:

 package main

 import (
 "fmt"
 "path/filepath"
 )

 func main() {

 filename := "start.txt"

 pattern := "*art*"

 matched, err := filepath.Match(pattern, filename)

 if err != nil {
 fmt.Println(err)
 }

 fmt.Println(matched)

 //---------------------------------

 pattern = "*fart*"

 matched, err = filepath.Match(pattern, filename)

 if err != nil {
 fmt.Println(err)
 }

 fmt.Println(matched)

 //---------------------------------

 filename = "data123.csv"

 pattern = "data[0-9]*"

 matched, err = filepath.Match(pattern, filename)

 if err != nil {
 fmt.Println(err)
 }

 fmt.Println(matched)

 }

Output :

true

false

true

NOTES: This example is for matching strings. For filenames in the current or specific directory. See this tutorial https://socketloop.com/tutorials/golang-use-wildcard-patterns-with-filepath-glob-example

It should work as well if you replace filepath.Match() with path.Match()
