I'd like to provide a program, for example a Python script, that can be run on platforms including Linux, Mac, and Windows. I want the program to read the content of a few files in the directory, and create a new file in that directory based on the content. Specifically, I want the program to find file1.txt and file2.txt, and create a new file file3.txt which is a concatenation of the first two files.
I might provide a Python script to a Linux user, and the user can run
python script.py
However, Windows does not have Python. What other choices of programs do I have that will allow it to be run on these platforms, without the user having to install anything extra?
You could use C++, but then you'd have to compile for each platform, which is sometimes more work than you'd like.
Most systems have some form of Java installed already, which could work.
Python runs on Windows, Mac and Linux, the user would just need to install it.
