I would like to get all the packages that contain the "nvidia" substring in their name, to sum up their size and print the total size in megabytes.
To do so I have written the following oneliner:



dpkg-query -Wf '$Installed-Sizet$Packagen' | sort -n | grep nvidia | awk -F' ' 'sum+=$1ENDprint sum/1024;'


But, how can I beautify it, make it as short as it is possible to be, keeping the functionality?



It is crooked-written for now, as you can see.






debian awk grep

          You can filter using dpkg-query itself, which means you don’t need to output the package name, and you don’t need to sort either:



          dpkg-query -Wf '$Installed-Sizen' '*nvidia*' | awk 'sum+=$1ENDprint sum/1024;'

                    One-line joke

                    A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
