“rpm query size”
RPM (Red Hat Package Manager) has an excellent --qf  (query format) option, which behaves much like printf function. Command rpm -q mozilla --qf '%{SIZE} will display the size of mozilla package. To list all packages with their sizes, you may use something like: 
\n'rpm -qa --qf '%-15{SIZE} %-30{NAME}\n' . The output of this command can be piped to sort -n to produce a list sorted by size.
