Hey,
You may also want to try out using
{{{
%sh
cd ~/
ls
}}}
in a cell, which would do what you want. However, if you want to
programatically use the results of these queries, one must use either
os.system('cd') or os.chdir('...'), as these are functions in the Python
library.
Please note that changing directories only affects one cell, for security
reasons.
