Nearly all of the concepts presented in this chapter apply to all Linux distributions. However, different Linux distributions may use different default environment files. Boot your Ubuntu Server Linux virtual machine and view the hidden environment files in your home directory. Which two files are used to store environment variables and aliases for each Ubuntu user by default? View their contents. Is there a /etc/profile and /etc/bashrc file by default? If not, what are they called? View the contents of both of these files.
