Here is an example workflow to run bash script, you can reference.

Script file (shell-scripts/

$1, $2 and $3 are the parameters that passed from outside when call script file.


echo "Hello $1"
echo "Current time is $2"

if [[ $3 == 1 ]]; then
  echo "Execute Function-1"
elif [[ $3 == 2 ]]; then
  echo "Execute Function-2"
  echo "Execute Function-3"

Workflow file

  • param1, param2 and param3 are the variables will be as parameters to pass into the script, they correspond to $1, $2 and $3 in the script.
  • Considering that the values of the passed parameters may contain whitespace, you’d better surround each parameter with the double quotes.
    runs-on: ubuntu-latest
      - name: Checkout
        uses: actions/checkout@v2.3.2

      - name: Run bash script
        shell: bash
        run: |
          chmod +x ./shell-scripts/
          param2=$(date +"%Y-%m-%d %H:%M:%S")
          ./shell-scripts/ "${param1}" "${param2}" "${param3}"

Is my above example workflow helpful to you?
Generally, most shell scripts use the similar methods to pass parameters from outside into the script files.
