Title: nix-collect-garbage
# Name
`nix-collect-garbage` - delete unreachable store paths
# Synopsis
`nix-collect-garbage` [`--delete-old`] [`-d`] [`--delete-older-than` *period*] [`--max-freed` *bytes*] [`--dry-run`]
# Description
The command `nix-collect-garbage` is mostly an alias of [`nix-store
--gc`](#rsec-nix-store-gc), that is, it deletes all unreachable paths in
the Nix store to clean up your system. However, it provides two
additional options: `-d` (`--delete-old`), which deletes all old
generations of all profiles in `/nix/var/nix/profiles` by invoking
`nix-env --delete-generations old` on all profiles (of course, this
makes rollbacks to previous configurations impossible); and
`--delete-older-than` *period*, where period is a value such as `30d`,
which deletes all generations older than the specified number of days in
all profiles in `/nix/var/nix/profiles` (except for the generations that
were active at that point in time).
# Example
To delete from the Nix store everything that is not used by the current
generations of each profile, do
$ nix-collect-garbage -d
