If the source_file ends in a /, the contents of the directory are copied rather than the directory itself. This option also causes symbolic links to be copied, rather than indirected through, and for cp to create special files rather than copying them as normal files. Created directories have the same mode as the corresponding source directory, unmodified by the process' umask. In -R mode, cp will continue copying even if errors are detected. Note that cp copies hard-linked files as separate files. If you need to preserve hard links, consider using tar(1), cpio(1), or pax(1) instead. ``` ### _How was this patch tested?_ - [ ] Add some test cases that check the changes thoroughly including negative and positive cases if possible - [ ] Add screenshots for manual tests if appropriate - [x] [Run test](https://kyuubi.readthedocs.io/en/latest/develop_tools/testing.html#running-tests) locally before make a pull request Closes #1463 from turboFei/tar_opt.
