How can I dump selected records using mysqldump?

Sometimes you just need to grab a few records from a table when using mysqldump.  Here's the syntax for doing that with a simple condition:

mysqldump -u [username] -h [host] -w "condition" -p [database] [table] > [output file]

I've used this successfully when needing to copy records, or insert new records with slightly different fields.  You can use a text editor on the resulting file to make mass changes to the sql.
