rm -r|--recursive foo            # Delete directory including contents

Creating Files

touch foo.txt          # Create file or update existing files modified timestamp
touch foo.txt bar.txt  # Create multiple files
touch {foo,bar}.txt    # Create multiple files
touch test{1..3}       # Create test1, test2 and test3 files
touch test{a..c}       # Create testa, testb and testc files

mktemp                 # Create a temporary file

Moving and Copy files

cp foo.txt bar.txt                                 # Copy file [cp file name spece destination]
mv foo.txt bar.txt                                 # Move file

nano                              # Open a new file in nano
nano foo.txt                      # Open a specific file

Finding Files

type -a wget                              # Display all locations of executable
which -a wget                             # Display all locations of executables 

update and upgrade

apt update                          # Refreshes repository index
