Contents|Index|Previous|Next Reject File Names The names for reject files (files containing patches that patch could not find a place to apply) are normally the name of the output file with '.rej' appended (or '#' on systems that do not support long file names). Alternatively, you can tell patch to place all of the rejected patches in a single file. The '-r reject-file' or'--reject-file= reject-file' option uses reject-file as the reject file name.
