I am trying to build a script that copies a specified number of lines from one document to multiple other documents. The copied lines are supposed to be appended to the end of the docs. In case I want to delete lines from the end of the docs, the script also has to be able to delete a specified number of lines.

I want to be able to run the script from the command line and want to pass two args:

1. "add" or "del"
2. number of lines (counting from the end of the document) A command could look like this: py doccopy.py add 2 which would copy the last 2 lines to the other docs, or: py doccopy.py del 4 which would delete the last 4 lines from all docs.

So far, I have written a function that copies the number of lines I want from the original document,
