What components and processes are usually implemented in Bash scripts for automating CI/CD pipelines?

Bash scripts for automating CI/CD typically include the following components and processes:

• Build the project: compilation, dependency installation.
• Run tests: unit tests, integration tests.
• Static code analysis: style and quality checks.
• Deployment: copying artifacts to a server or cloud.
• Error handling: checking command statuses and logging.
• Parameterization: using environment variables for configuration.

Example of a simple script fragment:

#!/bin/bash
set -e  # stop on error

# Install dependencies
composer install

# Run tests
vendor/bin/phpunit

# Deploy
scp -r ./build user@server:/var/www/project
