CentOS - Aug 2009 - replacing permissions on uploaded windows files

Hello,
	I've got a CentOS box and users are putting Windows long files on
it, files with " " and " - " in their filenames. I'm
trying to adjust the
permissions as well as user and group membership and i'd like the changes to
be sticky. On the tld i've set permissions of 2755 and am trying to batch
convert the files and subfolders in it. I've done this:

find tld -type f |xargs chmod 644 {} \;
find tld -type d |xargs chmod 755 {} \;

	Both of these are failing due to the spaces and dashes. I've tried
enclosing those {} in quotes, no good. Has anyone done this with shell or
perhaps perl?
Thanks.
Dave.

I believe what you want is 2775 and 664 (group writable), right?

Use "-print0" in find and "-0" in xargs. Also, you don't
need the "{}
\;", that is syntax for "find -exec" which you are not using.

I think what you want is:

$ find tld -type f -print0 | xargs -0 chmod 664
$ find tld -type d -print0 | xargs -0 chmod 2775

You've got 'find' syntax and 'xargs' syntax hopelessly
mingled.  Here:

     find tld -type f -print0 | xargs -0 chmod 644 --
     find tld -type d -print0 | xargs -0 chmod 755 --

The "-print0" and "-0" use the ASCII NUL character as the
argument
delimiter, so any legal path can be passed without being mangled.
The "--" tells chmod that none of the following arguments that might
begin with '-' should be treated as options.
