Как Направих Терминала Си Красив (И Дори Започнах Да Обичам Да Го Гледам По Цял Ден)

#!/usr/bin/env bash
# ============================================================================
#  terminal-glow.sh (v1.1 - fixed)
#  Transform a boring black-and-white terminal into something you actually
#  enjoy staring at for 10 hours a day.
#
#  What this installs:
#    - Zsh (shell)
#    - Oh My Zsh (framework)
#    - Powerlevel10k (theme with gorgeous git integration)
#    - zsh-autosuggestions (ghost-text history suggestions as you type)
#    - zsh-syntax-highlighting (live red/green feedback on commands)
#    - eza (modern ls replacement with colors and icons)
#    - bat (modern cat replacement with syntax highlighting)
#    - fd-find (modern find replacement)
#    - ripgrep (modern grep replacement)
#    - fzf (fuzzy finder for everything)
#    - Custom .zshrc with a hand-tuned aesthetic config
#    - Pre-configured Powerlevel10k prompt (no wizard needed)
#
#  Tested on: Ubuntu 22.04 / 24.04 / 26.04, Debian 11/12
#
#  Usage:
#    As your normal user with sudo access:
#      ./terminal-glow.sh
#
#    Or with sudo (will configure for the invoking user, not root):
#      sudo ./terminal-glow.sh
