Unless you also want to delete files in subdirectories of your current directory, using find to get the list of files with names ending in .trc is grossly inefficient compared to ls *.trc. Unless you're on a system with a small value for ARG_MAX, you can skip using xargs as well using:
The standards allow ARG_MAX to be as small as 4096, but on OS X it is 262144. You can find the value on your system using:
If the value returned is likely to be smaller than the number of bytes needed to hold the names of the files you'll be removing plus any environment variables you're exporting, you'll need to keep the xargs element of the pipeline rather than using the above form of command substitution.

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.
