Lesson 1 - Basic commands to navigate directories

pwd (Print Working Directory):

• Displays your current directory (or folder) within the terminal. It's useful to know where you are within the file system.

mkdir (Make Directory):

• Creates a new directory (or folder) in the specified location.

mkdir -v (Verbose Mode for mkdir):

• Creates a directory and prints a message for each directory created. The -v flag stands for "verbose" and tells you what action was performed.

mkdir -vp (Verbose + Parent Directories):

• Creates a directory along with any necessary parent directories. The -p option allows the creation of parent directories that don't exist yet, and the -v prints the actions.

ls (List):

• Lists the files and directories in the current working directory. It shows the names of items in the directory.

ls -R (Recursive List):

• Lists files and directories recursively, showing all files in the current directory and subdirectories.

cd ..:

• Moves you up one directory level (i.e., to the parent directory of your current directory).

cd - (minus sign):

• Switch back to the previous directory you were in before the last cd command. It acts as a toggle between two directories.

cd (with no arguments):

• It takes you back to your home directory, regardless of where you are in the file system.
