Try this then:
The PlaneShift updater application is actually in two parts: the GUI (which displays the pretty red & blue progress bars) and the updater engine (which downloads new files & replaces the old files with them.)
There has been a recurring problem on Windows with the GUI part of the app crashing after it\'s been run once; using the --auto switch allows you to run the updater even when you can\'t run the GUI.
I suspect this switch was intended to allow the updater to run as a scheduled background job. I recommend against this, however (and so do many other people in many other threads) until things are much more stable - a situation which, though still far in the future, draws visibly nearer with each update

As to how (forgive me if I assume Windows): In the Updater shortcut\'s Properties pane, find the field labeled \"Target\". It will contain something like
\"C:\\Program Files\\blah\\blah\\Planeshift\\updater.exe\" in quotes. After the closing quote, add
--auto so it looks like
\"C:\\Program Files\\blah\\blah\\Planeshift\\updater.exe\" --autoand you shoud be shiny.
I\'m not really familiar with the *nix GUIs, but I expect you would have to write a shell script with something like
$PLANESHIFT_HOME/updater --autoant then attach it to an icon somehow.
