- With spaces: `node file-upload-cli.js "my file.txt"`
### Step 3: Use the URL

## Security Considerations
### File Access
- The tool only reads the file you specify
- No directory traversal or unauthorized file access
- Files are not modified or deleted
- File path validation prevents malicious inputs
### Network Security
- Only communicates with `https://litterbox.catbox.moe` (HTTPS encrypted)
- Uses system curl command for secure file transmission
- No other external services are contacted
- No authentication tokens or API keys required
- Secure TLS connection for file transmission
### Data Privacy
⚠️ **Important**: Files are uploaded to a **public** file sharing service:
- URLs are publicly accessible by anyone who has the link
- Files automatically expire after 72 hours
- No authentication or access control
- Do not upload sensitive, confidential, or private files
- User is responsible for file content and compliance
### Dependencies
The tool uses:
- **Native Node.js modules**: `child_process`, `fs`, `path`, `util`
- **System curl**: Pre-installed on most systems, widely trusted and security-audited
- **No external npm packages required**
## Limitations
- **Maximum file size**: 1GB (litterbox.catbox.moe service limit)
- **File expiry**: Files are automatically deleted after 72 hours
- **Upload timeout**: 60 seconds
- **Single file**: One file per command (no batch uploads)
- **No retry logic**: Failed uploads must be manually retried
- **Public URLs**: All uploaded files are publicly accessible
- **Requires curl**: System must have curl installed
## Technical Details
**Implementation**: `file-upload-cli.js` (Node.js script)
