 Move `SOURCE` to `DEST`, or multiple `SOURCE`(s) to `DIRECTORY`.

+## After Help
+
+Do not move a non-directory that has an existing destination with the same or newer modification timestamp;
+instead, silently skip the file without failing. If the move is across file system boundaries, the comparison is
+to the source timestamp truncated to the resolutions of the destination file system and of the system calls used
+to update timestamps; this avoids duplicate work if several ‘mv -u’ commands are executed with the same source
+and destination. This option is ignored if the -n or --no-clobber option is also specified. which gives more control
+over which existing files in the destination are replaced, and its value can be one of the following:
+
+all    This is the default operation when an --update option is not specified, and results in all existing files in the destination being replaced.
+none   This is similar to the --no-clobber option, in that no files in the destination are replaced, but also skipping a file does not induce a failure.
+older  This is the default operation when --update is specified, and results in files being replaced if they’re older than the corresponding source file.
