# Cheat sheet
|
||
|
|
|
||
|
|
## Show GC roots
|
||
|
|
|
||
|
|
```sh
|
||
|
|
nix-store --gc --print-roots | grep -v "<hostName>" | column -t | sort -k3 -k1
|
||
|
|
```
|
||
|
|
|
||
|
|
## List all packages
|
||
|
|
|
||
|
|
```sh
|
||
|
|
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
|
||
|
|
|
||
|
|
```sh
|
||
|
|
nix path-info -hsr /run/current-system/ | sort -hrk2 | head -n10
|
||
|
|
```
|
||
|
|
|
||
|
|
## Find biggest closures (packages including dependencies)
|
||
|
|
|
||
|
|
```sh
|
||
|
|
nix path-info -hSr /run/current-system/ | sort -hrk2 | head -n10
|
||
|
|
```
|
||
|
|
|
||
|
|
## Show package dependencies as tree
|
||
|
|
|
||
|
|
> Assuming `hello` is in PATH
|
||
|
|
|
||
|
|
```sh
|
||
|
|
nix-store -q --tree $(realpath $(which hello))
|
||
|
|
```
|
||
|
|
|
||
|
|
## Show package dependencies including size
|
||
|
|
|
||
|
|
```sh
|
||
|
|
nix path-info -hSr nixpkgs#hello
|
||
|
|
```
|
||
|
|
|
||
|
|
## Show the things that will change on reboot
|
||
|
|
|
||
|
|
```sh
|
||
|
|
diff <(nix-store -qR /run/current-system) <(nix-store -qR /run/booted-system)
|
||
|
|
```
