#!/usr/bin/env bash # # install-synology-prompt.sh # # Universal installer for Synology SysAdmin Prompt. # # ------------------------------------------------------------------------------- # USAGE # ------------------------------------------------------------------------------- # # Recommended: # # bash install-synology-prompt.sh # # Do NOT normally run this installer using: # # sudo bash install-synology-prompt.sh # # The script will request sudo privileges itself when required. # # # What this installer does: # # 1. Verifies that the machine looks like Synology DSM. # 2. Verifies that Bash is available. # 3. Downloads synology-prompt.sh. # 4. Installs it as: # # /etc/synology-prompt.sh # # with: # # owner: root # group: root # mode : 0644 # # 5. Adds a small loader to the current user's ~/.profile. # 6. Preserves existing user configuration. # 7. Adds root integration to /root/.profile. # 8. Preserves Synology's original root profile. # 9. Makes "sudo -i" use Bash + the same prompt. # # # Requirements: # # - Synology DSM # - Bash # - sudo access # - wget or curl # # # Nerd Font: # # Nerd Font is NOT installed on Synology. # Install/use a Nerd Font in your SSH client or terminal. # # ------------------------------------------------------------------------------- set -u # ============================================================================== # CONFIGURATION # ============================================================================== PROMPT_URL="https://gist.darto.id/dartokloning/d0bd9f4e277a4242acbc7fb153c9a440/download/HEAD/synology-prompt.sh" PROMPT_FILE="/etc/synology-prompt.sh" USER_MARKER_BEGIN="# >>> Synology SysAdmin Prompt >>>" USER_MARKER_END="# <<< Synology SysAdmin Prompt <<<" ROOT_MARKER_BEGIN="# >>> Synology SysAdmin Prompt - Root >>>" ROOT_MARKER_END="# <<< Synology SysAdmin Prompt - Root <<<" # ============================================================================== # OUTPUT HELPERS # ============================================================================== info() { printf '\n== %s ==\n' "$1" } ok() { printf ' -> %s\n' "$1" } warn() { printf 'WARNING: %s\n' "$1" >&2 } die() { printf 'ERROR: %s\n' "$1" >&2 exit 1 } # ============================================================================== # DETECT CURRENT USER # ============================================================================== # The installer is intended to be launched as the normal DSM user. if [ "$(id -u)" -eq 0 ]; then die "Jalankan installer sebagai user DSM biasa, bukan dengan 'sudo bash'.
