Too many file names to type out?

The easiest way to handle large numbers of files is to use the * wildcard in the shell.

nbuild source_file* -o notebook.ipynb

You can use the ls command to assign all of the relevant names in the current directory to a variable and pass this variable as an argument.

Consider the example below:

touch {01..09}.py
name_list=`ls 0*.py`
nbuild `echo $name_list`

In Python environments, os.listdir can provide a list of all files:

from os import listdir
from os.path import isfile, join
onlyfiles = [f for f in listdir(mypath) if isfile(join(mypath, f))]

To preserve the order and differentiate files that should be incorporated into the notebook, it may be helpful to left pad file names with zeros (e.g. 01\_intro.md, 02\_figure1.R). This works well for R scripts, but Python files that start with numbers cannot be imported.
