Renames all files in the current directory such that the new file contains no space characters.
This is a better version, as it does no command piping, uses for instead of while loops, which allows for a list of files in the current working directory to be natively processed. It also uses the -v/verbose option with mv to let you know what the command is doing. While the command does exactly the same in a better way, I would modify the sed option to replace spaces with underscores instead, or dashes. Please note that you'll receive errors with this command as it tries to rename files that don't even have spaces.
