Other than the Ubuntu virtual machine with files from the previous chapters, no other resources are needed.
All scripts for this chapter can be found on GitHub: https://github.com/PacktPublishing/Learn-Linux-Shell-Scripting-Fundamentals-of-Bash-4.4/tree/master/Chapter08. For the name-improved.sh script only the final version is found online. Be sure to verify the script version in the header before executing it on your system.
