When using `curl` like that, it will output the contents of the Zip-file to the terminal (`curl` writes to standard output by default). This may well corrupt the terminal, just as when you `cat` a compressed file or any other binary file.
To save the file, use `curl -O ...`. This will save the file with its original name (`stuff.zip`) in the current directory.
To save it with another name, use either `curl -o newname ...` or `curl ... >newname`.
