Answer 1

you can use:

cat > youNewFile.someExtension

Example:

cat > myNewFile.txt

After you are done press Ctrl + d to save or Ctrl + c to abort (but in this case it's gonna save an empty file. The redirection operator ( > ) will create the file if it doesn't already exists in your folder and you will be able to edit it right a way through the terminal.
