This method creates a file name output.txt. If it already exists, its contents are erased and our output is written to it. We could also do this which is ./reader/sh names.txt and this time we do two greater than symbols and output.txt. Note that there are two greater than signs. This is similar to the first command except it doesn't erase the contents of the output file. Instead, it adds the new text to the bottom of the file. If we show what's inside of this file, so we do cat output.txt, we can see that it…
