- `--list-generations`\
Prints a list of all the current existing generations for the

# Name
`nix-collect-garbage` - delete unreachable store paths
`nix-collect-garbage` - delete unreachable [store objects]
# Synopsis
@ -8,17 +8,57 @@
# Description
The command `nix-collect-garbage` is mostly an alias of [`nix-store
--gc`](@docroot@/command-ref/nix-store/gc.md), 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).
The command `nix-collect-garbage` is mostly an alias of [`nix-store --gc`](@docroot@/command-ref/nix-store/gc.md).
That is, it deletes all unreachable [store objects] in the Nix store to clean up your system.
However, it provides two additional options,
[`--delete-old`](#opt-delete-old) and [`--delete-older-than`](#opt-delete-older-than),
which also delete old [profiles], allowing potentially more [store objects] to be deleted because profiles are also garbage collection roots.
These options are the equivalent of running
[`nix-env --delete-generations`](@docroot@/command-ref/nix-env/delete-generations.md)
with various augments on multiple profiles,
prior to running `nix-collect-garbage` (or just `nix-store --gc`) without any flags.
> **Note**
>
> Deleting previous configurations makes rollbacks to them impossible.
These flags should be used with care, because they potentially delete generations of profiles used by other users on the system.
## Locations searched for profiles
`nix-collect-garbage` cannot know about all profiles; that information doesn't exist.
Instead, it looks in a few locations, and acts on all profiles it finds there:
1. The default profile locations as specified in the [profiles] section of the manual.
2. > **NOTE**
>
> Not stable; subject to change
>
> Do not rely on this functionality; it just exists for migration purposes and is may change in the future.
> These deprecated paths remain a private implementation detail of Nix.
`$NIX_STATE_DIR/profiles` and `$NIX_STATE_DIR/profiles/per-user`.
With the exception of `$NIX_STATE_DIR/profiles/per-user/root` and `$NIX_STATE_DIR/profiles/default`, these directories are no longer used by other commands.
`nix-collect-garbage` looks there anyways in order to clean up profiles from older versions of Nix.
# Options
These options are for deleting old [profiles] prior to deleting unreachable [store objects].
- <span id="opt-delete-old">[`--delete-old`](#opt-delete-old)</span> / `-d`\
Delete all old generations of profiles.
This is the equivalent of invoking `nix-env --delete-generations old` on each found profile.
- <span id="opt-delete-older-than">[`--delete-older-than`](#opt-delete-older-than)</span> *period*\
Delete all generations of profiles older than the specified amount (except for the generations that were active at that point in time).
*period* is a value such as `30d`, which would mean 30 days.
This is the equivalent of invoking [`nix-env --delete-generations <period>`](@docroot@/command-ref/nix-env/delete-generations.md#generations-days) on each found profile.
See the documentation of that command for additional information about the *period* argument.

# Description
This operation deletes the specified generations of the current profile.
The generations can be a list of generation numbers, the special value
`old` to delete all non-current generations, a value such as `30d` to
delete all generations older than the specified number of days (except
for the generation that was active at that point in time), or a value
such as `+5` to keep the last `5` generations ignoring any newer than
current, e.g., if `30` is the current generation `+5` will delete
generation `25` and all older generations. Periodically deleting old
generations is important to make garbage collection effective.
*generations* can be a one of the following:
- <span id="generations-list">`<number>...`</span>:\
A list of generation numbers, each one a separate command-line argument.
Delete exactly the profile generations given by their generation number.
Deleting the current generation is not allowed.
- The special value <span id="generations-old">`old`</span>
Delete all generations older than the current one.
- <span id="generations-days">`<days>d`</span>:\
The last *days* days
*Example*: `30d`
Delete all generations older than *days* days.
The generation that was active at that point in time is excluded, and will not be deleted.
- <span id="generations-count">`+<count>`</span>:\
The last *count* generations up to the present
*Example*: `+5`
Keep the last *count* generations, along with any newer than current.
Periodically deleting old generations is important to make garbage collection
effective.
The is because profiles are also garbage collection roots — any [store object] reachable from a profile is "alive" and ineligible for deletion.

# Examples
## Delete explicit generation numbers
```console
$ nix-env --delete-generations 3 4 8
```
Delete the generations numbered 3, 4, and 8, so long as the current active generation is not any of those.
## Keep most-recent by count count
```console
$ nix-env --delete-generations +5
```
Suppose `30` is the current generation, and we currently have generations numbered `20` through `32`.
Then this command will delete generations `20` through `25` (`<= 30 - 5`),
and keep generations `26` through `31` (`> 30 - 5`).
## Keep most-recent in days
```console
$ nix-env --delete-generations 30d
```
This command will delete all generations older than 30 days, except for the generation that was active 30 days ago (if it currently exists).
## Delete all older
```console
$ nix-env --profile other_profile --delete-generations old
```

A *substituter* is an additional store from which Nix will
copy store objects it doesn't have. For details, see the
[`substituters` option](./command-ref/conf-file.md#conf-substituters).
An additional [store]{#gloss-store} from which Nix can obtain store objects instead of building them.
Often the substituter is a [binary cache](#gloss-binary-cache), but any store can serve as substituter.
