Howard,
Alternatively, if you have a directory tree in which you know
the permissions you'd like to have for files and directories,
you can set them all en masse. This probably runs fast enough
to suit you and avoids doing a bunch of manual work in the event
that there are lots of files with incorrect permissions.
To change directories::
find -type d -exec chmod 770 {} +
To change files::
find -type f -exec chmod 660 {} +
There are fancier options to ``chmod`` to adjust some permission
bits without changing others, but the above is pretty simple
when you know what you want for the entire set of permission
bits.
