Iterate run inscript command line tool over all html files in subfolders

I would like to convert a large number of html files to txt files. I have downloaded the inscript command line tool from github but I am struggling to apply it to all html files which are located in subdirectories and then save these files as text files in the same directory where the html files are located.

I have tried:

for f in ./ do inscript.py -o test.txt done

Solution

The following should work:

for d in ./**/*/; do
  pushd "$d"
  for f in *.html(N); do
    out=test-${f%.html}.txt
    inscript.py -o "$out" "$f"
  done
  popd
done

The pattern .**/*/ will recursively match the current directory and all its subdirectories. pushd will change to a directory, but remember the current working directory. inscript.py does its thing, then popd returns to the original working directory so that the next value of d continues to be a valid relative directory.

Changing the working directory isn't strictly necessary; it just simplifies the file paths involved, because you focus on the name of the file and ignore the rest of the path.
