|
`nix-env --set` - set profile to contain a specified derivation
|
|
|
|
## Synopsis
|
|
|
|
`nix-env` `--set` *drvname*
|
|
|
|
## Description
|
|
|
|
The `--set` operation modifies the current generation of a profile so
|
|
that it contains exactly the specified derivation, and nothing else.
|
|
|
|
{{#include ./opt-common.md}}
|
|
|
|
{{#include ../opt-common.md}}
|
|
|
|
{{#include ./env-common.md}}
|
|
|
|
{{#include ../env-common.md}}
|
|
|
|
## Examples
|
|
|
|
The following updates a profile such that its current generation will
|
|
contain just Firefox:
|
|
|
|
```console
|
|
$ nix-env --profile /nix/var/nix/profiles/browser --set firefox
|
|
```
