I have enabled data logging for a lot of signals in my model, how can do this via command line functions?

The following code will disable signal logging for all the signals in the model ('gcs' can be replaced by the model name):
mdlsignals = find_system(gcs,'FindAll','on','LookUnderMasks','all','FollowLinks','on','type','line','SegmentType','trunk');
ph = get_param(mdlsignals,'SrcPortHandle')
for i=1: length(ph)
set_param(ph{i},'datalogging','off')
end

For those who want to copy paste this into a laaarge model...
...add a semicolon on line 2.
My ph variable had an output of length 2077x1. :/

I made a convenient shortcut out of the following script.
% this will remove logging of any selected signals in the SimuLinkmodel
mn=inputdlg({'Input SimuLink Model Name:'},'',1,{''});
if ~isempty(mn)
if exist(mn{1})==4
mdlsignals = find_system(mn,'FindAll','on','LookUnderMasks','all','FollowLinks','on','type','line','SegmentType','trunk');
ph = get_param(mdlsignals,'SrcPortHandle');
for i=1: length(ph)
set_param(ph{i},'datalogging','off')
end
msgbox(['Any signal loggings in "',mn{1},'" have been removed.'])
else
msgbox(['"',mn{1},'" is not a valid SimuLink model.'])
end
end
