This is just a compilation of commend line options you can use with GSA. I found them scattered and collected them as I found them useful.
-deldupes
Removes duplicates from the global folders
-autostart
Automatically starts posting to active projects. Same as hitting the start button, but it does it at program launch
-close
Closes an existing open instance of SER
-noupdatecheck
Skips the update check at startup
-delhistory
Removes the url history for all projects
-scheduler
Automatically runs with scheduler options (last selection is saved)
