Pass a variable between jobs in Github Action

To set the output of a step in a Github Actions workflow and use it in a subsequent job, you can use the run command to save the output as an environment variable. Here's an example in YAML syntax:

yaml
jobs:
  job1:
    runs-on: ubuntu-latest
    steps:
      - name: Get output value
        run: echo "::set-output name=value::42"

  job2:
    runs-on: ubuntu-latest
    needs: job1
    steps:
      - name: Use output value
        run: echo "The value is ${{ steps.job1.outputs.value }}"

In the above example, job1 sets an output named value to 42. The second job, job2, depends on job1 and accesses the output using steps.job1.outputs.value.
