This example demonstrates a shell script that expands a Linux system’s swap space by adding an 8 GB swapfile. It first checks the `/etc/fstab` file for an existing swapfile entry, then creates and activates the swapfile using command-line utilities such as `fallocate`, `mkswap`, and `swapon`, and appends the necessary mount line. The script concludes by outputting system memory and swap details via `df`, `/proc/swaps`, and `grep` on `/proc/meminfo`. It uses no visualization libraries, relying solely on terminal output.

Script useful to resize or extend a disk on EC2

This example presents a shell script that automates disk resizing operations for Amazon EC2 instances. It shows the sequential process of first checking current disk space with `df -h`, then applying the `resize2fs` command with a user-specified partition name, and finally verifying the resize was successful. The script documents each step through inline comments, making it a practical reference for system administrators. The visualization highlights the clear workflow of examination, action, and validation through command-line tools on a Linux filesystem.

This example shows a shell script that automates the setup of a Linux-based scavenger hunt environment for students. It creates a local directory, downloads a Vagrantfile from a TinyURL link, and runs `vagrant up` to launch a virtual machine. The script then extracts the SSH host and port from `vagrant ssh-config` and prints connection instructions. The code relies on the Vagrant CLI, `curl`, and standard Unix utilities like `grep`, `awk`, and `sed`.

This example shows a bash script that automates the setup of a Linux scavenger-hunt lab environment. It downloads an SSH deploy key, clones a Git repository from GitLab, initializes submodules, and uses Vagrant to provision the virtual machine. The script concludes by parsing `vagrant ssh-config` output with `awk` and `sed` to display the student’s SSH connection details, including hostname and port.

This example shows a Bash script that automates the setup of a Linux scavenger-hunt lab environment, from downloading a deploy key to provisioning a virtual machine. The script uses `curl` to fetch an SSH private key, `git clone` and `git submodule update --init --recursive` to retrieve the lab definitions, and `vagrant up` to launch the machine. It then parses `vagrant ssh-config` output with `grep`, `awk`, and `sed` to extract the hostname and port, printing SSH connection instructions for the student user.

This example shows a shell script that automates the setup of a Linux scavenger hunt lab environment by downloading a deploy key, cloning a GitLab repository, and running Vagrant to provision the machine. The script uses `curl` to fetch an SSH key, `git clone` with submodules to pull the lab definitions, and `vagrant up` to launch the virtual machine. It then extracts the SSH hostname and port from `vagrant ssh-config` using `grep` and `awk`, printing connection instructions for the student user.

This example demonstrates a shell script that automates the setup of a Linux scavenger hunt lab environment. It creates a directory, clones a Git repository from GitLab, initializes submodules, and uses Vagrant to launch a virtual machine. The script then runs a PowerShell reprovisioner script and fixes line endings with `dos2unix` before executing the reprovisioning process. The visualization—if any—is not present; the code focuses purely on environment provisioning using Git, Vagrant, and PowerShell APIs.

Create a Logical Volume in Proxmox for shared data between LXCs

This example demonstrates how to create a dedicated logical volume for shared data across LXC containers in Proxmox. It shows the shell commands and system utilities required, including `lvcreate` to allocate a thin-provisioned volume named `shared-data` from the `pve/data` pool, `mkfs.ext4` to format it, and `mount` to attach it. The script writes an entry to `/etc/fstab` for persistence and reloads systemd. The visualization is plain-text code, not graphical, relying on command-line tools and file-editing rather than a data-rendering library.

This example demonstrates a Vagrant configuration for provisioning a Linux-based cybersecurity scavenger hunt environment. It defines a single virtual machine using the `cybersecurity/linux-scavenger` box, assigning it a private network IP and synced folder via SMB. The Vagrantfile uses the Hyper-V provider to allocate 2 GB of memory and one CPU, while explicitly disabling SSH key insertion for the guest. The setup relies on environment variables for SMB credentials, creating a reproducible lab environment for security exercises.
