# Ad-Hoc Package Management {#sec-ad-hoc-packages}
|
||||
|
||||
With the command `nix-env`, you can install and uninstall packages from
|
||||
the command line. For instance, to install Mozilla Thunderbird:
|
||||
|
||||
```ShellSession
|
||||
$ nix-env -iA nixos.thunderbird
|
||||
```
|
||||
|
||||
If you invoke this as root, the package is installed in the Nix profile
|
||||
`/nix/var/nix/profiles/default` and visible to all users of the system;
|
||||
otherwise, the package ends up in
|
||||
`/nix/var/nix/profiles/per-user/username/profile` and is not visible to
|
||||
other users. The `-A` flag specifies the package by its attribute name;
|
||||
without it, the package is installed by matching against its package
|
||||
name (e.g. `thunderbird`). The latter is slower because it requires
|
||||
matching against all available Nix packages, and is ambiguous if there
|
||||
are multiple matching packages.
|
||||
|
||||
Packages come from the NixOS channel. You typically upgrade a package by
|
||||
updating to the latest version of the NixOS channel:
|
||||
|
||||
```ShellSession
|
||||
$ nix-channel --update nixos
|
||||
```
|
||||
|
||||
and then running `nix-env -i` again. Other packages in the profile are
|
||||
*not* affected; this is the crucial difference with the declarative
|
||||
style of package management, where running `nixos-rebuild switch` causes
|
||||
all packages to be updated to their current versions in the NixOS
|
||||
channel. You can however upgrade all packages for which there is a newer
|
||||
version by doing:
|
||||
|
||||
```ShellSession
|
||||
$ nix-env -u '*'
|
||||
```
|
||||
|
||||
A package can be uninstalled using the `-e` flag:
|
||||
|
||||
```ShellSession
|
||||
$ nix-env -e thunderbird
|
||||
```
|
||||
|
||||
Finally, you can roll back an undesirable `nix-env` action:
|
||||
|
||||
```ShellSession
|
||||
$ nix-env --rollback
|
||||
```
|
||||
|
||||
`nix-env` has many more flags. For details, see the nix-env(1) manpage or
|
||||
the Nix manual.
