I actually don't really understand WHAT it is I did, but it worked like it was supposed to and I have to wonder what other efficiencies I could find with others tasks.
Back story: I had multiple text files, and I wanted to get all the contents merged into one text file, which I would then import into a spreadsheet to organize the data in columns. I googled to see if there was a way to merge the text files rather than opening each one to copy / paste the contents and LOW and BEHOLD there was! A thing that looked like code. And a screen shot of that black screen in my start menu. I found the black screen. I made a minor change to the code to find the files I wanted, in the location I needed. And it worked beautifully.
For those of you who know more about this, do you have a resource you can point me towards that will help me baby-step into how I can use the command line to be more efficient working with files or completing administrative tasks?
Thanks in advance!
