The same is happening myself I have put a space between the search name and the path to the directory and it still dosen't work
Each one of those is slightly different from what's in the instructions
Yes, that is one command, that all goes on one line. It breaks on a space, there is a space there.
The file system's root is /, if you omit the /, then you are giving a relative path from where you are now
The text to search for is Arctic, not Artic
