How do you apply Linux tools and capabilities in your professional activities?

In my professional activity, I use Linux as the main operating system for development and administration. The main tools and capabilities include:

• Command line (bash, zsh) — for task automation, scripting, and system management.
• Package management (apt, yum, pacman) — for installing and updating software.
• Monitoring and diagnostics (top, htop, ps, netstat, lsof) — for tracking process and network status.
• File and text processing (grep, awk, sed, find) — for searching and data processing.
• System administration (systemctl, journalctl) — for managing services and logs.
• SSH and remote access — for working with remote servers.
• Containerization (Docker, Podman) and virtualization — for environment isolation.

Example: using a bash script, you can automate data backups:

#!/bin/bash

tar -czf backup_$(date +%F).tar.gz /var/www/html

Thus, Linux provides a powerful set of tools for efficient work and automation.
