Lesson17_Delete_Convert: Deleting Files and Converting Jupyter Notebooks (.ipynb) to HTML

How to find your Jupyter nbconvert version

jupyter nbconvert --version

If you want to see what will be deleted first ... Run this safer command before deleting anything:

for /d /r %i in (.ipynb_checkpoints) do @echo %i

It will list every .ipynb_checkpoints directory that would be removed

The following command recursively finds and deletes all .ipynb_checkpoints directories starting from the current directory

for /d /r %i in (.ipynb_checkpoints) do @if exist "%i" rd /s /q "%i"

What it does

• for /d /r — Recursively traverses all subdirectories.
• %i — Stores the path of each matching directory.
• (.ipynb_checkpoints) — Looks for directories named .ipynb_checkpoints.
• if exist "%i" — Verifies that the directory exists.
• rd /s /q "%i" — Removes the directory and all of its contents without prompting.
• /s = Delete all files and subdirectories.
• /q = Quiet mode (no confirmation prompts).

How to delete all .ipynb_checkpoints folders under a certain folder

To start from a specific folder

For example, to delete all .ipynb_checkpoints folders under C:\Explore regardless of your current directory:

cd /d C:\Explore
for /d /r %i in (.ipynb_checkpoints) do @if exist "%i" rd /s /q "%i"

How to delete all .html files from the current directory

del /s /q *.html

will permanently delete every .html file in the current directory and all of its subdirectories.

What the options mean
del — Delete files.
/s — Include all subdirectories.
/q — Quiet mode (do not ask for confirmation).

How to recursively convert every Jupyter notebook (.ipynb) under the current directory to HTML

for /r %i in (*.ipynb) do jupyter nbconvert --to html "%i"

What it does
for /r — Recursively searches all subdirectories.
%i — Stores the full path of each .ipynb file.
jupyter nbconvert --to html — Converts the notebook to HTML.

How to add a progress message so you can see which notebook is being processed

for /r %i in (*.ipynb) do @echo Converting "%i" & jupyter nbconvert --to html "%i"

How to convert a particular .ipynb file to a HTML file

jupyter nbconvert --to html "C:\Explore\SAS\Combined_Lessons.ipynb"

How to convert multiple .ipynb files to HTML files on the same command line.

jupyter nbconvert --to html ^
"C:\Explore\SAS\Lesson1\Lesson1_Part1.ipynb" ^
"C:\Explore\SAS\Lesson14\Testing_Local_SAS_SASPy.ipynb"

How to convert multiple .ipynb files to HTML files on a single line.

jupyter nbconvert --to html "C:\Explore\SAS\Lesson1\Lesson1_Part1.ipynb" "C:\Explore\SAS\Lesson14\Testing_Local_SAS_SASPy.ipynb"
