ubuntu move all files in directory

mv /from/dirctory/* /to/drictory

linux move all files up a directory

mv myfolder/* .

Move all files from a folder in linux

mv source_path/* destination_path/

here you have to put forward slash and * after source path so that it will take files inside source_path instead of the complete source directory.
The above command moves all files (unless they are hidden) in the source directory to the destination directory.
