Study Notes

Creating Directories and File Management

Establish a new directory in the /tmp location to prevent unintentional changes to real files.
Use an absolute path with a forward slash at the beginning when executing the mkdir command to ensure the directory is created in the correct location.
The mkdir command stands for "make directory" and is used to create new folders.
Arguments or parameters can be passed to commands; mkdir requires at least one argument, whereas cd can operate without ones or with just one.
Commands like ls (list) can be used to view the contents of the current directory after creating subdirectories.

Structure and Nested Directories

By default, the mkdir command creates multiple directories at the same level without nesting.
The -p option allows for the creation of nested directories simultaneously, creating any necessary parent directories.
Options can modify command behavior and may be expressed as single characters (e.g., -p) or longer names (e.g., --option).
Different commands may represent options differently; understanding this variability is essential in command-line navigation.

Handling Spaces in Directory Names

Creating directories with spaces in their names requires special handling to avoid unintended results.
Use an escape character (backslash ) or quote marks to correctly create directories with spaces.
Proper formatting ensures that the command line interprets spaces as part of the directory name rather than as delimiters for separate arguments.
Working with spaces can complicate command line operations, emphasizing the importance of correct syntax.
