| * From cmd.exe /? output: |
| * </p> |
| * <p/> |
| * <pre> |
| * If /C or /K is specified, then the remainder of the command line after |
| * the switch is processed as a command line, where the following logic is |
| * used to process quote (") characters: |
| * |
| * 1. If all of the following conditions are met, then quote characters |
| * on the command line are preserved: |
| * |
| * - no /S switch |
| * - exactly two quote characters |
| * - no special characters between the two quote characters, |
| * where special is one of: &<>()@ˆ| |
| * - there are one or more whitespace characters between the |
| * the two quote characters |
| * - the string between the two quote characters is the name |
| * of an executable file. |
| * |
| * 2. Otherwise, old behavior is to see if the first character is |
| * a quote character and if so, strip the leading character and |
| * remove the last quote character on the command line, preserving |
| * any text after the last quote character. |
| * </pre> |
| * <p/> |
| * <p> |
| * Always quoting the entire command line, regardless of these conditions |
| * appears to make Windows processes invoke successfully. |
| * </p> |
| * |
| * @param executable The executable. |
| * @param arguments The arguments for the executable. |
| * @return The resulting command line. |
