find -exec

[aphro <nate@firetrail.com>]

What i wanna do ..is 2 things

find all files in a directory tree and chmod them 644

find all directories in a directory tree and chmod them 775

and i'm trying to do it with the find -exec command.  For the directory
part i did get this working:
chmod 7755 `find . -type d`

but for the file part chmod said there was too many files so i wanan try
to do it with the -exec option in find.  can someone give me a command
that would work for this ?  ive treid several variations on this command:

find . -exec chmod u+wx {} -type f

to no avail ..no matter what i do it keeps saying its "missing argument to
`-exec' i've tried escaping it with \ tried single and double quotes,
tried calling a single command with no arguements i moved the -exec
command to the end of the find command ARGH NOTHING! There are about 5,000
files i need to modify.

plz help someone :))
