CLI - Command-Line Interface

Creating, reading, updating, deleting and navigation on the command-line interface

Creating a folder

1. mkdir my_folder
2. ls to list all the content of the current working directory

Change into that folder

1. cd my_folder to change the current working directory into the new directory created
2. cd ../ to change to the previous directory

Move folder

mv my_folder /home/<user-name>/Desktop to move my_folder to the Desktop

Rename a folder

mv my_folder new_folder

Copy a folder

cp -r new_folder my_folder copies the content of new_folder into my_folder

Delete folder

rmdir new_folder rm -r new_folder when new_folder is not empty

Creating file

1. touch my_file
2. cat > my_file then Ctrl + C or Ctrl + D to create an empty file

Writing into a file

1. cat > my_file + Enter or Return - you then type the content of the file, followed by Ctrl + C when you are done cat >> my_file to append new content to the old content, without the second >, my_file will be over written
2. echo "string data" >> my_file to write text into my_file directly
3. cat my_file >> some_new_file to read the content of my_file into some_new_file and if some_new_file does not exist, it will be created

Copy a file

cp my_file my_new_file

Move file

mv my_file /home/<user-name>/Desktop/ to move my_file to the Desktop

Rename file

mv my_file new_file - Know that if new_file is a directory then my_file would be moved into new_file instead of renaming it

Delete file

rm new_file
