 # resrm
 
-**resrm** is a safe, drop-in replacement for the Linux `rm` command with **undo/restore support**.  
+**resrm** is a safe, drop-in replacement for the Linux `rm` command with **undo/restore support**.
 It moves files to a per-user _trash_ instead of permanently deleting them, while still allowing full `sudo` support for root-owned files.
 
 ---
 
 ## Features
 
-- Move files and directories to a **trash folder** instead of permanent deletion  
+- Move files and directories to a **Trash folder** instead of permanent deletion
-- Restore deleted files by **short ID or exact basename**  
+- Restore deleted files by **short ID or exact basename**
-- Empty trash safely  
+- Empty trash safely
-- Supports `-r`, `-f`, `-i`, `--perma` options  
+- Supports `-r`, `-f`, `-i`, `--skip-trash` options
-- Works with `sudo` for root-owned files  
+- Works with `sudo` for root-owned files
+- Automatically prunes Trash entries older than `$RESRM_TRASH_LIFE` days (default **7**, minimum **1**)
+  > Note: if you need immediate deletion, use the regular `rm` command instead.
+
+---
+
+## Configuration
+
+To control how long trashed files are kept, add this line to your shell configuration (e.g. `~/.bashrc`):
+
+```bash
+export RESRM_TRASH_LIFE=10
+```

+## pre-commit
+This project uses [**pre-commit**](https://pre-commit.com/) to run automatic formatting and security checks before each commit (Black, Bandit, and various safety checks).
+
+To enable it:
+```
+poetry install
+poetry run pre-commit install
+```
+This ensures consistent formatting, catches common issues early, and keeps the codebase clean.
