Random UUID

Random UUID is great when you need to generate a file with a temporary filename and avoiding file naming conflict.

Bash

No additional installation required for Bash, just run the command below.

uuidgen

Ruby

No additional installation required for Ruby too. Just copy the codes below into “uuid.rb”.

require 'securerandom'
puts SecureRandom.uuid

Use the command below to execute the Ruby script.

ruby uuid.rb

Go/Golang

The component to generate UUID does not come preinstalled together with the standard installation of Go/Golang. You’ll need to install the package by running the command below.

go get github.com/google/uuid

Paste the content below into “uuid.go”.

package main
import (
  "fmt"
  "github.com/google/uuid"
)
func main(){
  fmt.Println(uuid.New())
}

Use command below to run it.

go run uuid.go
