I want to know if there is a bash/shell script which I can use to automaticly update my instance so that I must not do this longer manually.

Also, because I am using a CMDLINE option in the main start script file this should be scanned and replaced so that there will be no errors (or the startscript files are skipped if they are not modified so we need a file with modified files/dirs which has to be overwritten).

Hopefully that smth. still exists.
