 # file-clean-rust
+
 Clean up (rename/delete) folders and files according to configured rules.
 
 ## Motivation
+
 Resources downloaded through P2P networks usually contain a lot of junk files or padding files.  
 Some clients (such as xunlei) have automatic cleaning features, but `aria2` lacks this functionality.  
 Therefore, I wrote a tool to clean up directories and files.

-## Configuration
+## Directory Monitoring
+
+The `monitor-dir.sh` script provides real-time monitoring of directories for newly moved folders.  
+When a directory is moved into the monitored path, it automatically runs `file-clean-rust` to clean it up.
+
+### Features
+
+- **Cross-platform support**: Works on Linux (using `inotifywait`) and macOS (using `fswatch`)
+- **Smart waiting mechanism**: Waits for directory to stabilize before processing to ensure all files are moved
+- **Safe path handling**: Correctly handles filenames with spaces and special characters
+- **Timeout protection**: Maximum wait time to prevent infinite waiting
+
+### Prerequisites
+
+**Linux/Unix systems:**
+
+```bash
+# Ubuntu/Debian
+sudo apt-get install inotify-tools
+
+# RHEL/CentOS/Fedora
+sudo yum install inotify-tools
+# or
+sudo dnf install inotify-tools
+```
+
+**macOS:**
+
+```bash
+brew install fswatch
+```
+
+### Script Usage
+
+```bash
+# Monitor a single directory
+./monitor-dir.sh /data/Downloads/TV/
+
+# Monitor multiple directories
+./monitor-dir.sh /data/Downloads/TV/ /data/Downloads/Movies/
+```
+
+### Script Configuration
+
+The script uses the following default settings:
+
+- **Maximum wait time**: 60 seconds
+- **Stability check time**: 3 seconds (waits for 3 seconds of no file activity)
+
+You can modify these values in the `wait_for_directory_stable()` function:
+
+```bash
+local max_wait=60     # Maximum wait time (seconds)
+local stable_time=3   # Stability time (seconds)
+```
+
+### How it works
+
+1. Monitors specified directories for `moved_to` events
+2. When a directory is moved in, starts monitoring that directory for file changes
+3. Waits until no file activity is detected for the stability period
+4. Runs `file-clean-rust --prune` on the stabilized directory
+5. Continues monitoring for new directory movements
+
+### Example Output
+
+```text

+[... file-clean-rust output ...]
+```
+
+## File Cleanup Configuration
 
 The default configuration file `.cleanup-patterns.yml` is searched for starting from the specified target path,  
 moving upwards step by step until the root directory is reached.
