Introduction to command line tools

What is a command line tool?

In the field of software development and system administration, command line tools (Command Line Interface - CLI) play an important role in helping programmers and system administrators perform their work more quickly, accurately and efficiently. Command line tools are programs that run on a terminal or command prompt, allowing users to enter text commands to perform tasks instead of manipulating them through a graphical interface (GUI).

Why are command line tools important?

Using command line tools not only helps programmers save time but also optimizes workflow, especially in web development, DevOps, and system management environments. Some outstanding benefits of command line tools include:

  • Increase working speed: Execute commands in just a few seconds instead of taking many steps on the graphical interface.
  • Process automation: Support writing scripts to automate repetitive work.
  • Save resources: Command line interface consumes less resources than GUI.
  • Better system control: Helps administrators perform detailed operations with the system that GUI cannot do.

Benefits of using command line tools in web development

Increase development speed

Using a command line tool allows you to quickly perform tasks such as project creation, library management, and application deployment without having to go through multiple steps in the graphical interface.

Process automation

Command-line tools support scripting to automate repetitive processes, reduce errors, and ensure consistency during development.

Save system resources

Command line interfaces often consume less resources than graphical interfaces, helping the system operate smoother, especially when working on low-configuration computers.

More comprehensive control

Using the command line allows programmers to have deeper and more granular control over systems and applications, making it easier to customize and optimize for specific needs.

Application of command line tools in web development

Command line tools have many applications in web programming, from software installation, system management to application testing and deployment. Here are some key areas where command line tools play an important role:

Source code management with Git

Git is the most popular distributed version management system today. Programmers use Git’s command line tool to:

  • Clone repository.
(git clone)
  • Commit changes.
(git commit -m "message")
  • Publish code to GitHub/GitLab
(git pu origin main).
  • Branch management.
(git branch, git checkout -b)

Manage library packages

NPM/Yarn (Node.js): Manages JavaScript libraries.

npm install package-name
yarn add package-name

Composer (PHP): Manage PHP dependencies.

composer require vendor/package

Create a rapid development environment

Docker CLI: Deploy application containers.

docker run -d -p 8080:80 my-container

Vagrant: Quickly create virtualized environments.

vagrant up

Testing and debugging

CURL/Wget: Test API and download files from server.

curl -X GET https://api.example.com/data

Lighthouse CLI: Evaluate website performance.

lighthouse https://example.com --output=json

Useful command line tools for web developers

Below is a list of the most popular and useful command line tools for web developers:

GitHub CLI

GitHub CLI is a command line tool that allows interaction with GitHub directly from the terminal. With GitHub CLI, you can do things like create a repository, manage pull requests, issues, and more without accessing the web interface. This increases productivity and integrates seamlessly with the development process. GitHub CLI helps programmers manage repositories on GitHub without using a browser. Some popular commands:

gh repo create my-repo --public
gh issue list
gh issue list
gh pr merge

HTTPie - API Testing

HTTPie is a command-line tool designed to make HTTP requests in a friendly and easy-to-use manner. It supports testing, debugging, and interaction with APIs. HTTPie provides clear syntax, colorful output, and supports features such as secure connections over HTTPS, proxy usage, authentication, header customization, and JSON parsing. HTTPie is an HTTP testing tool that makes working with REST APIs easier:

http GET https://jsonplaceholder.typicode.com/posts/1

Chrome Developer Tools CLI

Chrome Developer Tools (DevTools) is a set of tools integrated into the Google Chrome browser, allowing developers to test and debug web applications directly from the browser. DevTools provides features like DOM viewing and editing, network monitoring, performance analysis, and more. To open DevTools, you can press F12 or Ctrl + ift + I on Windows/Linux, or Cmd + Option + I on macOS. Chrome DevTools CLI supports debugging directly from the command line:

chrome --headless --disable-gpu --screenot https://example.com

Dirsearch - Scan website directories

Dirsearch is an open source tool written in Python that works in a brute-force fashion to explore directory and file structures on the web. It supports many options such as multithreading, searching by extension list, setting delay between requests, configuring cookies, user-agent, headers, and proxy. Dirsearch is useful for checking security and discovering hidden links on websites. Dirsearch helps scan hidden folders and files on websites:

python3 dirsearch.py -u https://example.com -e php,html

cURL - Testing HTTP Requests

xsel is a command-line utility that allows reading and writing to the X Selection clipboard on Unix/Linux systems. It is useful in dumping the output of a command to the clipboard or copying data from the clipboard into a command. This helps increase efficiency when working with text and commands in the terminal. cURL is one of the most popular tools for sending HTTP requests:

curl -X POST -H "Content-Type: application/json" -d '{"name":"John"}' https://api.example.com/users
