batch

[Pamela Hart]

My question is this: I need to input data from a .sql file into an 
existing and empty database I have created.

I type this into terminal at the main command line: mysql -uUser 
database_name < filename.sql.

I keep getting an error message that says no such file or directory 
exists.

I have tried every version of this command I can think of, including 
from within the mysql console.

Please help.
