Explanation

The command source ~/.bashrc should be executed first to use the alias command. The source command reads and executes commands from a file in the current shell environment. The ~/.bashrc file is a configuration file that contains commands and aliases that are executed when a new bash shell is started. The administrator made some changes in the ~/.bashrc file and added an alias command, but the changes are not effective until the file is sourced or a new shell is started. The command source ~/.bashrc will reload the file and make the alias command
