Cheat sheet
Show GC roots
nix-store --gc --print-roots | grep -v "<hostName>" | column -t | sort -k3 -k1
List all packages
nix-store -q --requisites /run/current-system | cut -d- -f2- | sort | uniq
You can add a wc -l at the end of the above command, but that will not be an accurate representation of
your package count, as the same package can be repeated with different versions.
Find biggest packages
nix path-info -hsr /run/current-system/ | sort -hrk2 | head -n10
Find biggest closures (packages including dependencies)
nix path-info -hSr /run/current-system/ | sort -hrk2 | head -n10
Show package dependencies as tree
Assuming
hellois in PATH
nix-store -q --tree $(realpath $(which hello))
Show package dependencies including size
nix path-info -hSr nixpkgs#hello
Show the things that will change on reboot
diff <(nix-store -qR /run/current-system) <(nix-store -qR /run/booted-system)
