I often load a database from a msqldump. The normal approach is to
cat the file through msql which works just fine. However, that
approach generates a lot of output that effectively hides any
errors. Worse yet, there is no indication of which record caused an
error so it can take many hours to figure out how to fix the problem.

I recommend adding a -q option to msql that will basically cause it
to only output error messages along with the query (generally an
insert of update record). The following changes to msql seem to work
fine for me:
