trash-cli は，元のパス・削除日時・パーミッションを記録した上でファイルをゴミ箱へ移動するツール

# Script: safe-rm
# Description:
#   Safely removes files or directories by moving them to the system trash
#   instead of permanently deleting them. Mimics 'rm -rf' behavior but uses
#   trash-cli or trash command for safety.
#
#   Steps:
#     1. Load required dependencies.
#     2. Detect available trash command (trash-put or trash).
#     3. For each argument, check existence and move to trash.
#
# Options:
#   (none) This script does not accept options; all arguments are treated as
#   files or directories to be trashed.
#
# Usage:
#   ./safe-rm <file-or-directory> [...]   # Move targets to trash safely
#
# Notes:
#   - Requires 'trash-cli' command installed.
#   - Does not permanently delete files; recovery is possible via trash.
#   - 'trash-restore' command can be used to recover trashed items.
#   - 'trash-empty' command can be used to permanently delete all items in trash.
