I have set up
aptitude update as cronjob for root and sending the mail to my normal user account.
What I want to have now, is that all the output of aptitude is ommited and instead only a summarization of all packages that are new or could be updgraded. Also in case of errors, there should be a list of errorous repos/ppa and the corresponding errormessage.
Is there a way to do such a cronjob, and where can I find informations about scripting such thing?
