List all the files or directories including hidden files

The ls command is used to list the files and directories in the current directory or a specified directory. It provides a way to view the contents of a directory.

Using the -a option is useful when you want to see all files and directories, including hidden ones, to get a complete view of the contents in a directory.

command - ls -a

Create a nested directory A/B/C/D/E

The mkdir command is used to create a new directory. A nested directory refers to a directory that is located within another directory.

command: mkdir -p A/B/C/D/E

The -p option allows you to create a directory and any necessary parent directories in the specified path.
