This assignment solution provides shell scripts for automated user account management, file system manipulation, and ZFS setup. The first script automates user creation based on data from a 'users.txt' file, generating random passwords and adding users to the system. The second script focuses on user removal, backing up the user's home directory before deletion. The solution also covers ZFS installation on Linux, including creating storage pools and snapshots for data backup. Additionally, it details how to modify user access rights using 'chown' and 'chmod' commands, and provides scripts for finding and removing specific file types. The final section includes scripts for various file system tasks, such as copying, creating, and deleting files and directories, and managing file permissions using PowerShell.
