Hallo, I need the information how many updates are available for a system. What is the best way to find it out in a one line bash script.
yum check-update, perhaps?
Note that "yum check-update" or "yum list updates" won't tell you how many packages would be installed with "yum update"... dependencies and such are not resolved for check-update/list updates.
otoh, its pretty rare that an update has a new dependency... if the package is installed, its existing dependencies are also installed, and if they have updates, check-update would show them all, would it not?
