What is the command that can be used to draw the directory tree inside the terminal emulator?

You can use tree to print the directory tree in terminal. Install tree from terminal,
sudo apt-get install tree
To see the directory tree, use
tree /path/to/folder
Or navigate to a directory and just use
tree
It has some advanced options too. You can see owner's username, groupname, date of last modification of a file/folder and so on using tree. It supports directory colors of ls so you can see colourized outputs.
See man tree for more.
You can do it easily with the following command:
find . -type d | sed -e "s/[^-][^\/]*\// |/g" -e "s/|\([^ ]\)/| - \1/"
This command will search recursively for directories inside the parent directory, and then draw the tree of the directories found.
You may also try the following to include all of the files as well.
find | sed 's|[^/]*/|- |g'
