From Tech Artists Wiki
Creating Batch (.bat) files and working with the Command Line is still necessary for the technical artist. It is often a requirement for having a script communicate with Source Control applications (Perforce, SubVersion, etc.). One can achieve some complex scripts with DOS, including logic and flow control. It should be a part of the technical artist toolbox, because even if it is not often used (and let's face it, there may be only a handful of times you'll need to write a DOS Batch script), it can do things certain scripting languages are unable to do (I'm looking at you, MaxScript and RMDIR).
- Wikipedia's List of DOS Commands is a worthwhile read for any technical artist who is not familiar with DOS scripting, and provides a solid overview of DOS scripting.
- http://www.computerhope.com/msdos.htm is one of the top sites around for learning how to use DOS. If you are creating a batch script, see their Batch File Help area.
