i want to check the rpm i have created is install or update by user(client) like
rpm -ivh abc.rpm
or
rpm -Uvh abc.rpm
is their any %command in spec file to get info regarding this command.
my requirement is if i have a rpm named abc-0.1-2.rpm and now user want to install it prior installing abc.0.1-1.rpm with command
rpm -ivh abc.0.1-2.rpm then it allow to install
or user directly update rpm with command rpm -Uvh abc.0.1-2 before installing the older version then stop to doing this.
Your %pre[un] and %post[un] scripts are given "a number representing the number of instances of the package currently installed on the system, after the current package has been installed or erased," so that tells you if the RPM is currently installed or not. See this section of Maximum RPM.
