+# Smart Backup & Restore Tool
+
+A versatile, hybrid Bash script for Linux that handles directory backups and restorations. It supports both a user-friendly **Interactive Menu** for manual use and a **Command Line Interface (CLI)** for automation and cron jobs.
+
+## 🚀 Features
+
+* **Hybrid Modes:** Use the interactive menu (`-i`) or command-line flags.
+* **Multiple Formats:** Support for `.tar.gz` (Standard), `.tar.bz2` (High Compression), and `.zip` (Windows compatible).
+* **Path Flexibility:** Choose between keeping the directory structure or a "Flat" backup (contents only).
+* **Smart Restore:** Auto-detects the archive format during restoration—no need to specify the file type manually.
+* **Safe:** Checks for required dependencies (`zip`, `unzip`) before attempting operations.
+
+## 📋 Prerequisites
+
+The script uses standard Linux tools. For `.zip` support, ensure you have `zip` and `unzip` installed:
+
+\`\`\`bash
+# Ubuntu/Debian
+sudo apt install zip unzip
+
+# RHEL/CentOS
+sudo yum install zip unzip
+\`\`\`
+
+## ⚙️ Installation
+
+1.  Download or create the script file:
+    \`\`\`bash
+    nano smart_backup.sh
+    \`\`\`
+2.  Paste the script code and save.
+3.  Make the script executable:
+    \`\`\`bash
+    chmod +x smart_backup.sh
+    \`\`\`
+
+## 📖 Usage
+
+Running the script without arguments displays the help menu:
+
+\`\`\`bash
+./smart_backup.sh
+\`\`\`
+
+### 1. Interactive Mode
+Best for manual, ad-hoc backups. This launches a text-based menu wizard.
+
+\`\`\`bash
+./smart_backup.sh -i
+\`\`\`
+
+### 2. Backup via CLI
+Best for scripts and automation.
+
+**Syntax:**
+\`\`\`bash
+./smart_backup.sh -b -s <SOURCE> -d <DESTINATION> [OPTIONS]
+\`\`\`
+
+**Examples:**
+
+* **Standard Backup (keeps folder name):**
+    \`\`\`bash
+    ./smart_backup.sh -b -s /var/www/html -d /backups
+    \`\`\`
+* **Backup with specific format (bzip2):**
+    \`\`\`bash
+    ./smart_backup.sh -b -s /home/user/docs -d /backups -t bz2
+    \`\`\`
+* **"Flat" Backup (contents only, useful for dumping files directly):**
+    \`\`\`bash
+    ./smart_backup.sh -b -s /var/log -d /tmp/logs -flat
+    \`\`\`
+
+### 3. Restore via CLI
+
+**Syntax:**
+\`\`\`bash
+./smart_backup.sh -r -f <BACKUP_FILE> -d <DESTINATION>
+\`\`\`
+
+**Example:**
+\`\`\`bash
+./smart_backup.sh -r -f /backups/html_20231010.tar.gz -d /var/www
+\`\`\`

+## 🚩 Argument Reference
+
+| Flag | Argument | Description |
+| :--- | :--- | :--- |
+| **-i** | None | Enter **Interactive Mode**. |
+| **-b** | None | Trigger **Backup Mode**. Requires \`-s\` and \`-d\`. |
+| **-r** | None | Trigger **Restore Mode**. Requires \`-f\`. |
+| **-s** | \`<path>\` | **Source** directory to backup. |
+| **-d** | \`<path>\` | **Destination** directory (for saving backup or unpacking restore). |
+| **-f** | \`<file>\` | **File** path of the archive to restore. |
+| **-t** | \`<type>\` | Compression type: \`gz\` (default), \`bz2\`, or \`zip\`. |
+| **-flat**| None | **Flat Mode**: Backs up files inside the folder, not the folder itself. |
+| **-h** | None | Show help/usage message. |
+
+## 🤖 Automation (Cron Job Example)
+
+To run a backup every day at 3:00 AM using this script:
+
+1.  Open crontab: \`crontab -e\`
+2.  Add the following line:
+
+\`\`\`cron
+0 3 * * * /path/to/smart_backup.sh -b -s /home/user/data -d /mnt/backups -t gz
+\`\`\`

+# change_uid.sh - Safe Linux UID Modification Script
+
+A robust, interactive bash script designed to safely change a user's User ID (UID) in Linux. 
+
+Changing a UID manually can leave behind orphaned files and cause system conflicts if the user has running processes. This script automates the safety checks, handles active processes, permanently changes the UID, and performs a surgical filesystem scan to update file ownership exactly where you need it.
+
+## ✨ Features
+
+* **Targeted Scanning (`--scan-path`):** Save time by restricting the file ownership update to a specific directory (e.g., `/home` or `/var/www`). Defaults to scanning the entire root (`/`) if omitted.
+* **Dry-Run Mode (`--dry-run`):** Safely simulate the entire process. See which processes would be killed and exactly which files would be modified without making any actual changes to your system.
+* **Custom Log Paths (`--log-dir`):** Save your audit logs to a centralized directory of your choosing (defaults to `/var/log` or `/tmp` for dry-runs).
+* **Process Management:** Detects if the target user is currently running any processes and provides an interactive prompt to safely terminate them before modifying the account.
+* **Collision Detection:** Verifies that your chosen new UID is not already taken by another user or system account.
+* **Detailed Auditing:** Generates a line-by-line log of every file modified, including the target scan path and timestamps. 
+
+## 📋 Prerequisites
+
+* **OS:** Linux
+* **Privileges:** Root access (`sudo`) is required to modify users and change system-wide file ownership.
+* **Dependencies:** Standard coreutils (`usermod`, `find`, `chown`, `pgrep`, `pkill`)
+
+## 🚀 Installation
+
+Clone the repository and make the script executable:
+
+```bash
+# Clone the repository
+git clone [https://github.com/YOUR_USERNAME/YOUR_REPOSITORY.git](https://github.com/YOUR_USERNAME/YOUR_REPOSITORY.git)
+
+# Navigate into the directory
+cd YOUR_REPOSITORY
+
+# Make the script executable
+chmod +x change_uid.sh
+```
+(Note: Replace YOUR_USERNAME and YOUR_REPOSITORY with your actual GitHub details).
+
+## 💻 Usage
+The script is interactive. Execute it with sudo and follow the on-screen prompts to enter the username and the new UID. You can append optional flags to customize its behavior.
+
+Basic Execution (Scans entire filesystem)
+```bash
+sudo ./change_uid.sh
+```
+
+### Targeted Scan (Recommended for speed)
+Limit the file ownership updates to a specific folder, such as the user's web directory.
+
+```bash
+sudo ./change_uid.sh --scan-path /var/www/html
+```
+### Dry-Run (Simulation)
+Highly recommended before making permanent changes. Simulates the update on a specific directory and outputs the simulated log to a custom folder.
+
+```bash
+sudo ./change_uid.sh --dry-run --scan-path /home --log-dir /tmp/uid_tests
+```
+### Custom Log Directory
+Direct the output logs to a specific folder. If the directory does not exist, the script will attempt to create it automatically.
+
+```bash
+sudo ./change_uid.sh --scan-path /opt/data --log-dir /opt/admin/logs
+```
+### Help Menu
+```bash
+sudo ./change_uid.sh --help
+```
+## ⚠️ Important Safety Notes
+Time Consumption: If you do not provide a --scan-path, the script runs a full filesystem scan (find /). This can take several minutes on systems with large hard drives or network-attached storage.
+
+Virtual Filesystems: The script intelligently ignores /proc, /sys, and /dev to prevent permission errors and speed up scans.
+
+Symlinks: The script uses chown -h to change the ownership of symbolic links themselves, rather than following the link and accidentally changing the target file's owner.
+
+Backups: Always ensure you have a backup of critical system configurations before modifying user accounts.

+# SSH Key Setup Script for User `mgveliz`
+
+## 📋 Overview
+This repository contains a Bash script (`setup_ssh_mgveliz.sh`) designed to automate the provisioning of SSH access for the user **mgveliz**. 
+
+It ensures that the SSH directory structure exists, applies the correct security permissions (chmod 700/600), and safely appends the specific public key to the `authorized_keys` file without creating duplicates.
+
+## 🚀 Features
+* **Safety Checks:** Verifies the target user exists before running.
+* **Idempotency:** Checks if the specific public key already exists to avoid duplicate entries.
+* **Security Compliance:** Enforces strict permissions:
+    * `~/.ssh` directory: **700** (`drwx------`)
+    * `authorized_keys` file: **600** (`-rw-------`)
+* **Ownership Fix:** Ensures all files are owned by `mgveliz:mgveliz` regardless of who runs the script (sudo).
+
+## 🛠️ Prerequisites
+* **OS:** Linux (Debian, Ubuntu, RHEL, SUSE, etc.)
+* **Privileges:** Must be run with `sudo` or as root.
+* **User:** The target user `mgveliz` must already exist on the system.
+
+## 💻 Usage
+
+1.  **Download or Clone the script** to the server.
+
+2.  **Make the script executable:**
+    ```bash
+    chmod +x setup_ssh_mgveliz.sh
+    ```
+
+3.  **Run the script with sudo:**
+    ```bash
+    sudo ./setup_ssh_mgveliz.sh
+    ```
+
+## 🔍 Script Logic Breakdown
+
+| Step | Action | Details |
+| :--- | :--- | :--- |
+| 1 | **Check User** | Verifies `id mgveliz` returns a valid user. Exits if not found. |
+| 2 | **Create Dir** | Creates `/home/mgveliz/.ssh` if missing (`mkdir -vp`). |
+| 3 | **Perms (Dir)** | Sets `.ssh` folder to `700`. |
+| 4 | **Append Key** | Greps the `authorized_keys` file for the specific key string. Appends only if missing. |
+| 5 | **Perms (File)** | Sets `authorized_keys` file to `600`. |
+| 6 | **Ownership** | Runs `chown -R mgveliz:mgveliz` on the `.ssh` folder to ensure the user owns their own keys. |
+
+## 🔑 Key Details
+The script installs the following RSA key (associated with `mgveliz@oxya.com`):
+
+> `ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDLSV3...`
+
+## ⚙️ Customization
+To use this script for a different user, modify the variables at the top of `setup_ssh_mgveliz.sh`:
+
+```bash
+TARGET_USER="new_username"
+KEY_CONTENT="ssh-rsa AAAA..."

+# NFS Client Setup Script
+
+This script automates the process of mounting an NFS (Network File System) share from a remote server to a local directory on a Linux client.
+
+## 📦 Features
+- Accepts server IP, mount directory, and remote share path as arguments
+- Validates if the mount point exists and prompts the user
+- Mounts the NFS share from the server
+- Displays a summary of the mount
+- Optionally adds the mount to `/etc/fstab` for persistence
+
+## ⚙️ Requirements
+- Linux system with NFS client utilities installed (`nfs-utils` or `nfs-common`)
+- Root or sudo privileges
+
+## 🚀 Usage
+```bash
+sudo ./nfs_client_setup.sh <SERVER_IP> <MOUNT_DIR> <REMOTE_DIR>
+```
+
+### Example
+```bash
+sudo ./nfs_client_setup.sh 192.168.1.10 /mnt/nfs/shared /srv/nfs/shared
+```
+
+## 📁 Output
+- Creates the mount point if it doesn't exist
+- Mounts the NFS share from the specified remote directory
+- Displays the current mount status
+
+## 📌 fstab Option
+After mounting, the script will ask if you want to make the mount permanent by adding an entry to `/etc/fstab`. This ensures the NFS share is mounted automatically on system boot.
+
+## 📄 License
+This script is provided as-is without warranty. Use at your own risk.

+# Static IPv4 Configuration Script for NetworkManager (`nmcli`)
+
+This repository contains a hardened Bash script that automates the process of configuring a static IPv4 address on Linux systems using **NetworkManager** (`nmcli`).  
+It includes full error handling, rollback capabilities, validation logic, and optional dry-run mode for safe change previews.
+
+---
+
+## 📌 Features
+
+- Configure IPv4 static addressing with:
+  - IP address + prefix
+  - Gateway
+  - DNS servers (optional)
+- Automatic detection of active `nmcli` connection profile
+- Comprehensive error handling and exit codes
+- Automatic **backup** of existing connection profile
+- Rollback on failure (restores original `.nmconnection`)
+- Timeout support for slow networking services
+- Dry-run mode for change validation
+- Safe logging with clear `[INFO]`, `[WARN]`, and `[ERROR]` blocks
+- IPv4 format validation for correctness and safety
+
+---
+
+## 📂 Script File
+
+The script shipped with this repository:
+
+```
+set-static-ip-nmcli.sh
+```
+
+Make it executable:
+
+```bash
+chmod +x set-static-ip-nmcli.sh
+```
+
+Run as root (required by NetworkManager):
+
+```bash
+sudo ./set-static-ip-nmcli.sh ...
+```
+
+---
+
+## 🚀 Usage
+
+### Basic static IP configuration
+
+```bash
+sudo ./set-static-ip-nmcli.sh   -i ens192   -a 10.54.240.204   -p 25   -g 10.54.240.129
+```
+
+### Add DNS servers
+
+```bash
+sudo ./set-static-ip-nmcli.sh   -i ens192   -a 10.54.240.204   -p 25   -g 10.54.240.129   -d 8.8.8.8,1.1.1.1
+```
+
+### Adjust nmcli timeout
+
+```bash
+sudo ./set-static-ip-nmcli.sh -t 30 ...
+```
+
+### Dry-run mode (no changes made)
+
+```bash
+sudo ./set-static-ip-nmcli.sh --dry-run   -i ens192   -a 10.54.240.204   -p 25   -g 10.54.240.129
+```
+
+---
+
+## 📝 Parameters
+
+| Flag | Description | Required |
+|------|-------------|----------|
+| `-i` | Network interface (`ens192`, `eth0`, etc.) | ✔ |
+| `-a` | IPv4 address | ✔ |
+| `-p` | Prefix length (`25` for `/25`) | ✔ |
+| `-g` | Default IPv4 gateway | ✔ |
+| `-d` | One or more DNS servers (comma-separated) | ✘ |
+| `-t` | Timeout (seconds) for `nmcli` operations | ✘ |
+| `--dry-run` | Do not apply — only show commands | ✘ |
+| `-h` | Show help | ✘ |
+
+---
+
+## 🔒 Rollback and Backup
+
+Before modifying anything, the script exports a full backup:
+
+```
+backup-<connection-name>-YYYYMMDD-HHMMSS.nmconnection
+```
+
+If any command fails during configuration or interface restart:
+
+- The script **automatically imports** the backup
+- Attempts to restore the previous connection state
+
+You can manually restore a backup at any time:
+
+```bash
+sudo nmcli connection import type file file backup-file.nmconnection
+```
+
+---
+
+## 🧪 Verification
+
+After applying changes, the script prints:
+
+- IPv4 address on the interface
+- Default routes
+- NetworkManager connection summary
+
+If verification fails, the script exits with a failure code.
+
+---
+
+## ❗ Exit Codes
+
+| Code | Meaning |
+|------|---------|
+| `0` | Success |
+| `1` | Not root / `nmcli` missing |
+| `2` | Invalid arguments / validation failure |
+| `3` | Interface or connection profile missing |
+| `4` | Backup export failed |
+| `5` | Failed to apply IPv4 settings |
+| `6` | Failed to restart connection |
+| `7` | Verification failure |
+| `8` | Rollback failed; manual fix required |
+
+---
+
+## ⚠️ Remote Server Warning
+
+Running:
+
+```
+nmcli connection down <profile>
+```
+
+**will disconnect your SSH session**.
+
+If using this script over SSH, consider:
+
+- Running inside a console (iLO, iDRAC, VMware console)
+- Using `at` or `systemd-run` to schedule a rollback if the server becomes unreachable
+
+Ask if you want an automated rollback timer added.
+
+---
+
+## 🛠 Requirements
+
+- Linux with **NetworkManager**
+- `nmcli` available in `$PATH`
+- Root privileges (`sudo`)

+```python
+readme_content = """# SAP Environment Sync Script
+
+A robust, interactive Bash script designed to securely synchronize SAP instance directories (such as `ASCS` and primary application servers) across environments using `rsync`.
+
+## 🌟 Features
+
+* **Interactive Execution:** Prompts the user before synchronizing each directory, allowing for granular control.
+* **Dry-Run Mode:** Includes a `--dry-run` flag to simulate the transfer and safely review what will be copied or deleted without making actual changes.
+* **Comprehensive Logging:** Automatically generates timestamped log files capturing both standard output and errors.
+* **Strict Error Handling:** Captures pipeline errors accurately and aborts subsequent synchronizations if a directory fails, preventing inconsistent partial states.
+* **Permission Preservation:** Utilizes `rsync` flags (`-aHAX`) specifically chosen to preserve critical SAP ACLs, extended attributes, and numeric IDs across systems.
+
+## 📋 Prerequisites
+
+* **OS:** Linux (Bash shell)
+* **Packages:** `rsync` must be installed on both the source and target servers.
+* **Access:** SSH passwordless access (key-based authentication) configured for the target user (e.g., `root`) to the target IP.
+
+## ⚙️ Configuration
+
+Before running the script, open it in your preferred text editor (like `vim` or `nano`) and adjust the variables at the top to match your environment:
+
+
+```
+
+```text
+File generated successfully.
+
+```bash
+TARGET_IP="10.84.242.225"      # The destination server IP
+TARGET_USER="root"             # The user used for the SSH connection
+SID="SP1"                      # The SAP System ID
+LOG_DIR="/var/log/sap_sync"    # Directory where logs will be stored
+
+```
+
+*Note: Ensure the user executing the script has write permissions to the `LOG_DIR`.*
+
+## 🚀 Usage
+
+### 1. Make the script executable
+
+First, ensure the script has the correct execute permissions:
+
+```bash
+chmod +x sync_script.sh
+
+```
+
+### 2. Standard Execution
+
+Run the script interactively. It will pause and ask for confirmation before syncing each path defined in the `directories` array.
+
+```bash
+./sync_script.sh
+
+```
+
+### 3. Dry-Run Execution (Recommended for first use)
+
+Test the synchronization safely. This will output exactly what rsync *would* do without transferring any data.
+
+```bash
+./sync_script.sh --dry-run
+
+```
+
+## 📂 Targeted Directories
+
+By default, the script is configured to synchronize the following standard NetWeaver/ABAP paths:
+
+* `/usr/sap/<SID>/ASCS01/sec/`
+* `/usr/sap/<SID>/D00/sec/`
+* `/usr/sap/<SID>/D00/log/`
+* `/sapmnt/<SID>/`
+
+You can modify the `directories` array in the script to add or remove paths as needed.
+
+## 📝 Logging
+
+Logs are automatically stored in `/var/log/sap_sync/` (or your configured `LOG_DIR`).
+Each run creates a unique file formatted as `sync_YYYYMMDD_HHMMSS.log`. You can review these logs for auditing purposes or to troubleshoot any failed transfers.

+# SAPinst Execution Wrapper
+
+A robust Bash script designed to automate and simplify the execution of the SAP Software Provisioning Manager (`sapinst`). This script handles remote access configuration, Certificate Revocation List (CRL) validation, and environment pre-checks.
+
+## 🚀 Features
+
+* **Pre-execution Validation:** Ensures the `sapinst` binary and necessary CRL files are present before attempting execution, preventing partial starts or confusing installer errors.
+* **Dynamic Hostname Detection:** Automatically detects the server's short hostname to configure the GUI hostname parameter accurately.
+* **Remote GUI Configuration:** Pre-configures trusted remote access for a specific user.
+* **Clear Logging & Error Handling:** Provides emoji-based console outputs for quick visual feedback and captures/returns standard exit codes.
+
+## 📋 Prerequisites
+
+Before running this script, ensure the following conditions are met:
+
+1.  **Location:** The script must be placed and run from the same directory as the `sapinst` executable.
+2.  **Permissions:** The script requires execution permissions (`chmod +x run_sapinst.sh`). You must also have the appropriate OS permissions (usually `root`) to run SAPinst.
+3.  **CRL File:** Ensure the CRL file (`crlbag.p7s`) has been downloaded and placed in the directory specified by the `SAPINST_CRL_PATH` variable.
+
+## ⚙️ Configuration
+
+The script contains several hardcoded variables at the top of the file. You should modify these to match your specific environment and user requirements before running:
+
+| Variable | Description | Default Value |
+| :--- | :--- | :--- |
+| `SAPINST_USER` | The OS user permitted to remotely access the SAP GUI. | `mgveliz` |
+| `SAPINST_TRUSTED` | Designates if the remote user is trusted. | `true` |
+| `SAPINST_CRL_PATH` | Absolute path to the local CRL file. | `/usr/sap/trans/MGW_Files/MGWADM/swpm/crlbag.p7s` |
+| `SAPINST_INST` | Absolute path to the SWPM installation directory. | `/usr/sap/trans/MGW_Files/MGWADM/swpm/INST_DIR` |
+| `SAPINST_CRL_SOURCE_URL` | The remote source URL for the CRL validation. | `https://tcs.mysap.com/crl/crlbag.p7s` |
+
+## 💻 Usage
+
+1. Navigate to the directory containing your unpacked SWPM/sapinst files:
+   ```bash
+   cd /path/to/swpm/

+# SAProuter Management Script
+
+This repository provides a **Bash script** to manage SAProuter with full lifecycle commands (`start`, `stop`, `status`, `restart`) and extended configuration options.
+
+---
+
+## Features
+- **Start/Stop/Status/Restart** SAProuter easily.
+- Supports **trace level control**:
+  - `--no-trace` disables trace.
+  - `--trace-level <n>` sets custom trace level.
+- Includes **extended SAProuter options**:
+  - `-r` : Run as router.
+  - `-Y 0` : Disable timeout for inactive connections.
+  - `-C 1000` : Maximum number of clients.
+  - `-D` : Run as daemon.
+  - `-J 20000000` : Jump buffer size.
+  - `-W 10000` : Maximum waiting connections.
+  - `-K "<cert>"` : Use specified certificate.
+- **Logging**: Output stored in `saprouter.log`.
+- **PID management**: PID stored in `saprouter.pid`.
+
+---
+
+## Usage
+
+```bash
+saprouter_manager.sh {start|stop|status|restart} [OPTIONS]

+# PowerShell Script: Find Largest Files and Folders
+
+This PowerShell script helps you identify the **largest files and folders** in a specified directory. It is interactive and allows you to:
+
+- Enter the **target directory path**
+- Filter files by **minimum size (in MB)**
+- Specify how many **top items** to display
+- View results for both **files and folders**
+
+---
+
+## Features
+✔ Interactive prompts for directory, size filter, and number of items  
+✔ Displays **largest files** and **largest folders** separately  
+✔ Sizes shown in **MB**  
+✔ Works recursively through subdirectories

+# Rename Spaces to Underscores (PowerShell)
+
+A PowerShell script to **recursively rename files and folders**, replacing spaces (" ") with underscores ("_"), with **dry-run**, **logging**, and **undo** capabilities.
+
+---
+
+## ✨ Features
+
+- ✅ Renames **files and directories**
+- ✅ Recursive operation
+- ✅ **Dry-run mode** (preview changes safely)
+- ✅ **Timestamped CSV log files**
+- ✅ **Undo (redo)** support using the latest log
+- ✅ Safe for deeply nested folder structures
+- ✅ Built-in PowerShell help (`Get-Help` supported)
+
+---
+
+## 🚀 Usage
+
+### Preview changes (Dry-Run)
+```powershell
+.\Rename-SpacesToUnderscore.ps1 -Path "C:\Data" -DryRun
+```
+
+### Perform renaming
+```powershell
+.\Rename-SpacesToUnderscore.ps1 -Path "C:\Data"
+```
+
+### Undo last rename (Preview)
+```powershell
+.\Rename-SpacesToUnderscore.ps1 -Path "C:\Data" -Undo -DryRun
+```
+
+### Undo last rename (Execute)
+```powershell
+.\Rename-SpacesToUnderscore.ps1 -Path "C:\Data" -Undo
+```
+
+---
+
+## 🧾 Logging
+
+Each run creates a timestamped log file:
+```
+rename_log_YYYYMMDD_HHMMSS.csv
+```
+
+The log is required for undo operations.
+
+---
+
+## 📖 Built‑in Help
+
+```powershell
+Get-Help .\Rename-SpacesToUnderscore.ps1 -Examples
+```
+
+---
+
+## ⚠️ Best Practices
+
+- Always run with `-DryRun` first
+- Keep log files until changes are verified
+- Do not run multiple instances in parallel

+.SYNOPSIS
+Renames files and folders by replacing spaces with underscores.
+
+.DESCRIPTION
+This script recursively renames files and directories by replacing
+blank spaces (" ") with underscores ("_").
+
+Features:
+- Works on files AND folders
+- Recursive
+- Timestamped CSV log file
+- Dry-run mode (preview only)
+- Undo (redo) capability using the latest log file
+
+.PARAMETER Path
+The root directory to process.
+Default is the current directory.
+
+.PARAMETER DryRun
+Preview all rename operations without making any changes.
+
+.PARAMETER Undo
+Reverts the most recent rename operation using the latest log file.
+Can be combined with -DryRun.
+
+.EXAMPLE
+Preview changes only:
+.\Rename-SpacesToUnderscore.ps1 -Path "C:\Data" -DryRun
+
+.EXAMPLE
+Perform renaming:
+.\Rename-SpacesToUnderscore.ps1 -Path "C:\Data"
+
+.EXAMPLE
+Preview undo:
+.\Rename-SpacesToUnderscore.ps1 -Path "C:\Data" -Undo -DryRun
+
+.EXAMPLE
+Undo last rename:
+.\Rename-SpacesToUnderscore.ps1 -Path "C:\Data" -Undo
+
+.NOTES
+Author: Your Name
+Log files are stored in the target Path.
+Undo relies entirely on the latest rename_log_*.csv file.
+Always run DryRun before executing changes in production.

+# top-ram.sh
+
+`top-ram.sh` is a Bash script that displays the top processes consuming the most **RAM (Resident Set Size - VmRSS)** on a Linux system. It provides detailed information including PID, process name, RAM usage in kilobytes, and the full command line used to launch the process.
+
+## Features
+
+- Lists processes using RAM, sorted by usage.
+- Supports filtering by:
+  - Specific usernames (`-u` or `--user`)
+  - Specific UIDs (`-U` or `--uid`)
+  - Current user only (`--mine`)
+- Output options:
+  - Pretty-printed table (default)
+  - Tab-separated values (`--tsv`)
+- Show top N processes (`-n`)
+- Show all processes with non-zero RAM usage (`--all`)
+- Optionally include a user column (`--show-user`)
+
+## Requirements
+
+- Bash 4+
+- Standard Unix utilities: `awk`, `sort`, `head`, `tr`, `id`, `getent`
+
+## Usage
+
+
+bash ./top-ram.sh

+# top-swap.sh — Top processes by swap usage (with full command lines)
+
+`top-swap.sh` scans `/proc` to show the **top processes by swap usage** on Linux, including **PID**, **Name**, optional **User**, **Swap (kB)**, and the **full command line**. It’s efficient (reads `cmdline` only for the top entries) and supports user filtering and machine-friendly TSV output.
+
+---
+
+## ✨ Features
+
+- 🔎 Shows **PID**, **Name**, **Swap (kB)**, and **full command line**
+- 👤 Optional **User** column with `--show-user`
+- 🔐 **User filtering**: `--mine`, `-u user1[,user2]`, `-U uid1[,uid2]`
+- 🧮 Choose **top N** with `-n N` or show **all** with `--all`
+- 📄 **TSV output** (`--tsv`) for scripting
+- 🧵 Gracefully handles kernel threads / unreadable `cmdline` (prints `[Name]`)
+- 🚀 Designed for speed: reads `/proc/<pid>/cmdline` **only** for top rows
+
+---
+
+## 🧩 Requirements
+
+- **Linux** with `/proc` mounted
+- **Bash 4+** (associative arrays)
+- Tools: `awk`, `sort`, `head`, `tr`, `id`, `getent`
+- Permissions: You may need `sudo` on systems using `hidepid` or to read other users’ `cmdline`
+
+Check your Bash version:
+
+echo "$BASH_VERSION"
+
+## 🧭 Usage
+
+./top-swap.sh
+./top-swap.sh --show-user
+./top-swap.sh --tsv | column -t -s $'\t'
+
+## 🧪 Examples
+
+./top-swap.sh -n 20 --show-user
+./top-swap.sh --mine
+sudo ./top-swap.sh -u postgres -U 0 --show-user

+
+Options:
+  -n N             Show top N processes by swap (default: 10)
+  --tsv            Output as tab-separated values
+  --all            Show all processes with non-zero swap (no top limit)
+  --mine           Show only processes owned by the current user (real UID)
+  -u, --user USER  Filter by username (repeatable or comma-separated)
+  -U, --uid UID    Filter by numeric UID (repeatable or comma-separated)
+  --show-user      Include a User column (pretty & TSV)
+  -h               Show this help
+
+Notes:
+  - Use 'bash ./top-swap.sh' (not 'sh'). Run with sudo if /proc is restricted.
+  - Filtering uses Real UID from /proc/<pid>/status (Uid: line).
+  - Kernel threads or unreadable cmdlines are shown as [Name].
