Приходилось ли писать Bash-скрипты для автоматизации? Насколько глубоко работали с Linux?

Yes, I have written Bash scripts to automate routine tasks such as backups, application deployment, and service monitoring.

My work with Linux was quite extensive: configuring system services, managing users and permissions, working with the file system, analyzing logs, and setting network parameters.

Here's an example of a simple script for automatic directory backup:

#!/bin/bash

BACKUP_DIR="/backup/$(date +%F)"
SOURCE_DIR="/var/www"

mkdir -p "$BACKUP_DIR"
tar -czf "$BACKUP_DIR/www_backup.tar.gz" "$SOURCE_DIR"

This experience allows me to automate tasks efficiently and maintain infrastructure stability.
