I know there should be a simple way to do this, but I'm having a hard time finding this online.
Let's say that I have a directory with a bunch of text files, and I want to cat them all together.
cat *.txt > output.txt
does the job, but there aren't new line characters at the end of each of these text files, so the last line of each file is merged with the first line of the next file.
My question: how do I cat a group of files together, but throw a new line character between each file?
