Have to ask ... are you simply copying and pasting without editing?
If so, that won't work for everything shared by others. Example: the word 'SECRET' is your password. Your passwords, if secure passwords, will probably have a mix of characters/symbols. So that the shell doesn't get confused and thinks one of those characters is something it's supposed to act upon, enclose the password in between 'ticks'.
Example: 'M00dlE!'
Also, the user 'root' was used in the example. More than likely, on a shared system, you will not be able to use the user 'root'. You have to use the 'user' setup with your database that has ability to interact with the DB's for your account.
Finally, think it best to check with the system administrator/service provider about running shell scripts. Could be a policy issue with provider.
