  travis show

  Shows the configuration for the current repository, including settings and environment variables.

• Update repository configuration:

  travis config

  Updates the configuration for the current repository. This can include environment variables, build settings, and more.

• Set environment variables:

  Provides help information for a specific <command>.

• List all commands:

  travis help

  Lists all available commands and provides a brief description.

Advanced Techniques

• Using .travis.yml for Configurations: Ensure your repository has a .travis.yml file for configuring builds. This YAML file specifies the build environment, language, and scripts to run.

• Matrix Builds: Configure matrix builds in .travis.yml to run tests across multiple environments. Example:

  matrix:
    include:
      - os: linux
        dist: xenial
        language: python
        python: 3.6
      - os: osx
        language: python
        python: 3.7

• Deployments: Configure automatic deployments in .travis.yml to deploy to various services upon successful builds. Example:

  deploy:
    provider: s3
    access_key_id: $AWS_ACCESS_KEY_ID
    secret_access_key: $AWS_SECRET_ACCESS_KEY
    bucket: my-bucket
    region: us-east-1
    local-dir: build/

• Conditional Builds: Use conditionals to run certain builds based on the branch or tags:

  jobs:
    include:
      - stage: test
        script: ./run_tests.sh
        if: branch = master

• Custom Build Scripts: Define custom build scripts for more complex workflows. Example:

  script:
    - ./custom_script.sh
