`-update` | Overwrite if source and destination differ in size, blocksize, or checksum | As noted in the preceding, this is not a "sync" operation. The criteria examined are the source and destination file sizes, blocksizes, and checksums; if they differ, the source file replaces the destination file. As discussed in the Usage documentation, it also changes the semantics for generating destination paths, so users should use this carefully.
`-append` | Incremental copy of file with same name but different length | If the source file is greater in length than the destination file, the checksum of the common length part is compared. If the checksum matches, only the difference is copied using read and append functionalities. The -append option only works with `-update` without `-skipcrccheck`
`-f <urilist_uri>` | Use list at \<urilist_uri\> as src list | This is equivalent to listing each source on the command line. The `urilist_uri` list should be a fully qualified URI.
+`-filters` | The path to a file containing a list of pattern strings, one string per line, such that paths matching the pattern will be excluded from the copy. | Support regular expressions specified by java.util.regex.Pattern.
`-filelimit <n>` | Limit the total number of files to be <= n | **Deprecated!** Ignored in the new DistCp.
`-sizelimit <n>` | Limit the total size to be <= n bytes | **Deprecated!** Ignored in the new DistCp.
`-delete` | Delete the files existing in the dst but not in src | The deletion is done by FS Shell. So the trash will be used, if it is enable.
