2006-09-19* `show-duplication.pl', a small utility that shows the amount ofEelco Dolstra
package duplication present in (e.g.) a profile. It shows the number of instances of each package in a closure, along with the size in bytes of each instance as well as the "waste" (the difference between the sum of the sizes of all instances and the average size). $ ./show-duplication.pl /nix/var/nix/profiles/default gcc 11 3.3.6 19293318 3.4.4 21425257 ... average 14942970, waste 149429707 coreutils 6 ... average package duplication 1.87628865979381, total size 3486330471, total waste 1335324237, 38.3017114443825% wasted This utility is useful for measuring the cost in terms of disk space of the Nix approach.
