If you have problems reloading the table due to the order

Our backups are quick large - over 500 MB. Opening the file and adding the above line at the top takes a lot of CPU time and memory - and when I'm restoring, I don't have a lot of time...
Is there an easier way to get it there - can I 'cat' to the beginning of a file, or should I make my backup scripts cat the output of mysqldump to the end of a file with 'set foreign_key_check=0;' at the top? Maybe we could have a switch for mysqldump that does this for us?



quick solution:
put the line "SET FOREIGN_KEY_CHECKS = 0;" in a file (eg.header.txt) and then:


cat header.txt mysql.dump >mysqlgood.dump

should take about 5 secs.
