This is quick SVN (Subversion) tip, howto remove added file from SVN repository without deleting file from local filesystem.
Remove File From SVN Repository and Keep Local File
svn delete --keep-local path/to/file.example
svn delete --keep-local css/test.css
Real world usage example
Adding a whole directory add a file that was not intended to SVN reads, but should be retained locally.
svn add css/ A css A css/testing_styles.css A css/style.css
style.css is OK, but testing_styles.css should not be commited, but it should be kept on locally. Simply remove it from svn but keep it locally:
svn delete --keep-local css/testing_styles.css D css/testing_styles.css
File is deleted from SVN repository, but kept locally:
svn status A css ? css/testing_styles.css A css/style.css
