Remove All Subversion Unversoned Files and Directories Automatically

---

svn status | grep ^\? | cut -c9- | xargs -d \n rm -r

Ref: http://stackoverflow.com/questions/239340/automatically-remove-subversion-unversioned-files

Note:

1. In "cut -c9-", "-c" means character, "9-" means retaining all characters from the 9th to the end of each line of input file;

2. In "xargs -d \n...", -d specifies the delimiter, here it's the carriage return(\n);
