UNIX

Proficiency with UNIX and UNIX-like operating systems, such as Linux, is a cornerstone skill for nearly every professional PHP developer. Since the vast majority of web servers that run PHP applications are based on these systems, a solid understanding of the command-line environment is essential for development, deployment, and server maintenance.

Why UNIX Skills are Crucial for PHP Developers

PHP developers use UNIX-based systems daily to manage their development environments and production servers. Skills in this area go beyond writing code and are critical for a streamlined workflow. This includes managing server software like Nginx or Apache, configuring PHP-FPM, and automating tasks with shell scripts.

Common UNIX Command-Line Tasks

A developer's comfort with the command line directly impacts their efficiency. Employers look for candidates who can perform essential server-side operations with ease.

• Server Access: Using SSH to securely connect to and manage remote servers.
• File System Navigation: Working with files and directories using commands like ls, cd, cp, and mv.
• Process Management: Monitoring and controlling running processes and services.
• Scripting: Writing simple Bash or Zsh scripts to automate deployment or maintenance tasks.
• Tooling: Using command-line tools like Composer, Git, and various testing utilities.
