3. Task 1 ✅: Check your present working directory.

To check your present working directory in Linux, you can use the “pwd” command. Open the terminal and simply type “pwd” followed by pressing the “Enter” key. The command will display the full path of the directory you are currently in. This will help you know where you are in the file system while navigating and executing commands.

To list all the files and directories, including hidden files, in the current directory in Linux, you can use the “ls” command with the “-a” option.

To create a nested directory A/B/C/D/E in Linux, you can use the “mkdir” command with the “-p” option to create parent directories as needed. To visualize nested directories in a tree-like structure, utilize the “tree” command. However, before using it, ensure you have the “tree” command installed by running “sudo apt-get install tree”.
