How to create random uuid in a github action

Question

Howdo i create a random uuid from a github action? I found a third party github action that creates a random uuid but i am hoping there is some native action that already supports this scenario.

Answer 1

With a Linux runner you can use uuidgen:

name: Test linux job
on:
  push

jobs:
  testJob:
    name: Test
    runs-on: ubuntu-latest
    steps:
      - run: |
          uuidgen

This will output the uuid to the console. You can then redirect the output to a file or a variable with the standard shell mechanisms.

Answer 2

as an improvement to the answer from @riQQ

name: Test linux job
on:
  push

jobs:
  testJob:
    name: Test
    runs-on: ubuntu-latest
    steps:
      - name: Get uuid
        id: uuid
        run: | 
            echo "::set-output name=uuid::$(uuidgen)"
