Piping tar archive via mv on macOS

Question

I ran:
tar -cjvf ~/Dict_$(date +%Y-%m_%d-%H_%M_%S).tar.bz2 ~/Dictionaries | xargs mv ~/Documents

but it leaves the resulting file in ~/ and does not move it.
How do I move the resulting file (after it was archived) to another folder?

Did you look at the output? 
Did it say something like
mv: target ‘some filename’ is not a directory?

In general, if cmd outputs a, b and c, and you run
cmd | xargs d e f
then xargs will rund e f a b c
So your command caused xargs to runmv ~/Documents file1 file2 file3 …
That’s not how mv works.

Try(your tar command)  |  xargs mv -t ~/Documents

Note: you should probably first verify that the version of mv
on your system supports the -t option. 
If you were on Linux, it would be pretty much guaranteed,
but I’m not sure about macOS.
