== Why <hash>-<name> instead of <name>-<hash>? ==

For the rare cases where we have to dig into the /nix/store it is more practical to keep in mind the first few letters at the beginning than finding a package by name. ~~In addition~~, the hash is ~~printed by Nix commands~~. If you still wonder why, run <code>ls -1 /nix/store | sort -R -t - -k 2 | less</code> in your shell.

For the rare cases where we have to dig into the /nix/store it is more practical to keep in mind the first few letters at the beginning than finding a package by name.

Ie, you can uniquely identify almost any storepath with just the first 4-5 characters of the hash.

Rather then having to type out the full package name, then 4-5 characters of the hash.

Also: since the initial part is all of the same length, visually parsing a list of packages is easier.

If you still wonder why, run <code>ls -1 /nix/store | sort -R -t - -k 2 | less</code> in your shell.

This is what might happen if you don't garbage collect frequently, or if you are testing compilation variants:
