# Delete __XLDIR__ Directory Scripts
|
||||
|
||||
This directory contains scripts for deleting all directories ending with `__XLDIR__` in the specified path.
|
||||
|
||||
## Script Description
|
||||
|
||||
### 1. delete_xldir.sh (Full Version)
|
||||
|
||||
A feature-rich version with multiple options and safety checks.
|
||||
|
||||
**Usage:**
|
||||
```bash
|
||||
./scripts/delete_xldir.sh <path> [options]
|
||||
```
|
||||
|
||||
**Options:**
|
||||
- `-f, --force` Force deletion without confirmation
|
||||
- `-v, --verbose` Show verbose information
|
||||
- `-d, --dry-run` Show directories to be deleted without actually deleting
|
||||
- `-h, --help` Show help information
|
||||
|
||||
**Examples:**
|
||||
```bash
|
||||
# Preview directories to be deleted (without actually deleting)
|
||||
./scripts/delete_xldir.sh /path/to/search --dry-run
|
||||
|
||||
# Interactive deletion (will ask for confirmation)
|
||||
./scripts/delete_xldir.sh /path/to/search
|
||||
|
||||
# Force deletion (without confirmation)
|
||||
./scripts/delete_xldir.sh /path/to/search --force
|
||||
|
||||
# Verbose mode deletion
|
||||
./scripts/delete_xldir.sh /path/to/search --verbose
|
||||
```
|
||||
|
||||
### 2. delete_xldir_simple.sh (Simple Version)
|
||||
|
||||
A streamlined version that directly deletes found directories.
|
||||
|
||||
**Usage:**
|
||||
```bash
|
||||
./scripts/delete_xldir_simple.sh <path>
|
||||
```
|
||||
|
||||
**Example:**
|
||||
```bash
|
||||
# Delete all directories ending with __XLDIR__ in the specified path
|
||||
./scripts/delete_xldir_simple.sh /path/to/search
|
||||
```
|
||||
|
||||
## How It Works
|
||||
|
||||
Both scripts use the `find` command to locate directories:
|
||||
```bash
|
||||
find "$SEARCH_PATH" -type d -name "*__XLDIR__"
|
||||
```
|
||||
|
||||
- `-type d`: Only search for directories
|
||||
- `-name "*__XLDIR__"`: Find directories ending with `__XLDIR__`
|
||||
|
||||
## Safety Notes
|
||||
|
||||
⚠️ **Important Reminders:**
|
||||
- Deletion operations are irreversible, please confirm the path is correct before use
|
||||
- It's recommended to use the `--dry-run` option first to preview directories to be deleted
|
||||
- For important data, please backup first
|
||||
|
||||
## Use Cases
|
||||
|
||||
These scripts are typically used for cleaning up temporary directories or metadata directories in storage systems, especially in distributed storage systems where `__XLDIR__` is commonly used as a specific directory identifier.
