# This script automatically downloads and installs the appropriate Netrinos client
# for the current system architecture. It should be run with superuser privileges.
#
# Usage:
#   sudo ./install-client.sh [version] [cli]
#
# or directly from the shell with:
#
# curl -fsSL https://dist.netrinos.com/linux/install-client.sh | sudo bash -s [version] [cli]
#
# Parameters:
#   version - latest (default), daily, beta, or specific version number
#   cli     - optional flag to install CLI-only version (no GUI)
#
# The script first detects the system architecture, then downloads the appropriate
# .deb package from the Netrinos distribution server. After downloading, it installs
# the package using dpkg.
#
# Examples:
#   bash -s latest       # Install latest UI version
#   bash -s daily cli    # Install daily CLI-only version
#   bash -s cli          # Install latest CLI-only version

# Detect the system architecture
detected_arch=$(uname -m)

# Parse arguments - look for 'cli' flag anywhere in args
cli_mode=false
version="latest"

for arg in "$@"; do
    arg_lower=${arg,,}
    if [ "$arg_lower" = "cli" ]; then
