Terminal command to move one directory into other


I want to move or sync my old project into new project directory


You can achieve this by sycn your old directory with new
terminal command to sync is :- 
sudo rsync -r source_directory_path destination_directory_path this will create complete clone of old directory into new one including its main directory name
sudo rsync -r source_directory_path/* destination_directory_path/  it will move files and folder in old directory to new directory without create a complete clone of old directory
