but it didn't work.

Could you explain me why.
First, you should explain to us. How did it not work? Show us the error messages. If there weren't any, then at least show us an example of the file hierarchy before running the command, after running the command, and how it should have been after running the command.

You say you "need to clean all days". What is a "day"? A directory? A file? Again, show us a sample of the filesystem hiearchy.

Is everything to be deleted in a single directory, or will find descend into subdirectories? If it will descend, will you be deleting only files, only directories, or both? Depending on the exact nature of the task, a depth-first traversal may be necessary. Again, a better explanation of what's going on is required.

Why are you using -name '*'? That will always evaluate to true. It's redundant.

Alister

svn-clean

SVN-CLEAN(1)							   User Commands						      SVN-CLEAN(1)

NAME

       svn-clean - Wipes out unversioned files from Subversion working copy

SYNOPSIS

       svn-clean [options] [directory or file ...]

DESCRIPTION

       svn-clean will scan the given files and directories recursively and find unversioned files and directories (files and directories that are
       not present in the Subversion repository). After the scan is done, these files and directories will be deleted.	Files which match patterns
       in the svn-clean:ignore dir property will be spared, much as the svn:ignore property works for svn status.

       If no file or directory is given, svn-clean defaults to the current directory (".").

       svn-clean uses the SVN Perl modules if they are available. This is much faster than parsing the output of the svn command-line client.

OPTIONS

       -e, --exclude
	       A regular expression for filenames to be exluded. For example, the following command will skip files ending in ".zip":

		       svn-clean --exclude '.zip$'

	       Multiple exclude patterns can be specified. If at least one matches, then the file is skipped. For example, the following command
	       will skip files ending in ".jpg" or ".png":

		       svn-clean --exclude '.jpg$' --exclude '.png$'

	       The following command will skip the entire "build" subdirectory:

		       svn-clean --exclude '^build(/|$)'

       -f, --force
	       Files to which you do not have delete access (if running under VMS) or write access (if running under another OS) will not be
	       deleted unless you use this option.

       -N, --non-recursive
	       Do not search recursively for unversioned files and directories. Unversioned directories will still be deleted along with all their
	       contents.

       -q, --quiet
	       Do not print progress info. In particular, do not print a message each time a file is examined, giving the name of the file, and
	       indicating whether "rmdir" or "unlink" is used to remove it, or that it's skipped.

       -p, --print
	       Do not delete anything. Instead, print the name of every file and directory that would have been deleted.

       -?, -h, --help
	       Prints a brief help message and exits.

       --man   Prints the manual page and exits.
