I have a .txt file with more than 6000 paragraphs and each paragraph is a short sentence. I want to create a shortcut to open the whole txt file, create new txt files, and change the title of each file to be a paragraph from the original file. Moreover, the new files should be ordered in the order of the paragraphs in the original file. Is there a way to do that on Mac?
So complicated job, how does a shortcut do that? 
Ask someone who’s an expert to help you out. I think that only the Terminal can resolve this task.
Your description is not clear. Do you mean that you want to find a shortcut to duplicate your original .txt file into 6000 copies and each copy is named with a paragraph in the original file in order?
If that’s what you mean, Jesus, a troublesome issue. You can press Command + C to copy the file and press Command + V to paste it into the target location, 6000 times, and then copy the paragraphs one by one from the original file, select the duplicate files one by one, and then press Return to change the file name orderly. That’s all that I can think of.
It seems that there’s no shortcut for your complex task. Maybe you need to run some commands in Terminal to achieve that.
This method isn’t easy, still thanks for your suggestions.
