Documentation on "classic" commands with many sub-commands are notoriously hard to discover due to lack of overview and anchor links. Additionally the information on common options and environment variables is not accessible offline in man pages, and therefore often overlooked by readers. With this change, each sub-command of nix-store and nix-env gets its own page in the manual (listed in the table of contents), and each own man page. Also, man pages for each subcommand now (again) list common options and environment variables. While this makes each page quite long and some common parameters don't apply, this should still make it easier to navigate as that additional information was not accessible on the command line at all. It is now possible to run 'nix-store --<subcommand> --help` to display help pages for the given subcommand. Co-authored-by: Valentin Gagarin <valentin.gagarin@tweag.io>

# Name
|
||
|
||
`nix-store --delete` - delete store paths
|
||
|
||
# Synopsis
|
||
|
||
`nix-store` `--delete` [`--ignore-liveness`] *paths…*
|
||
|
||
# Description
|
||
|
||
The operation `--delete` deletes the store paths *paths* from the Nix
|
||
store, but only if it is safe to do so; that is, when the path is not
|
||
reachable from a root of the garbage collector. This means that you can
|
||
only delete paths that would also be deleted by `nix-store --gc`. Thus,
|
||
`--delete` is a more targeted version of `--gc`.
|
||
|
||
With the option `--ignore-liveness`, reachability from the roots is
|
||
ignored. However, the path still won’t be deleted if there are other
|
||
paths in the store that refer to it (i.e., depend on it).

{{#include ./opt-common.md}}
|
||
|
||
{{#include ../opt-common.md}}
|
||
|
||
{{#include ../env-common.md}}
|
||
|
||
# Example
|
||
|
||
```console
|
||
$ nix-store --delete /nix/store/zq0h41l75vlb4z45kzgjjmsjxvcv1qk7-mesa-6.4
|
||
0 bytes freed (0.00 MiB)
|
||
error: cannot delete path `/nix/store/zq0h41l75vlb4z45kzgjjmsjxvcv1qk7-mesa-6.4' since it is still alive
|
||
```
