Change current working directory from MySQL client prompt

Is there anyway to change the current working directory from the MySQL client prompt?

That would allow me to use relative paths for the tee, source, and another command which I don’t recall just now (I just noticed that the post got truncated my copy/pasting, and I had listed a few example commands in the original text file draft — being new to MySQL, I’m that familiar with the commands off the top of my head).

I found from other apps that changing the working directory is extremely useful in general, e.g., in Vim and Matlab.

You can’t. There is no code in the mysql client executable to change directory.
