<para>
|
|
This command shows the version of the currently active NixOS configuration.
|
|
For example:
|
|
<screen><prompt>$ </prompt>nixos-version
|
|
16.03.1011.6317da4 (Emu)
|
|
</screen>
|
|
The version consists of the following elements:
|
|
<variablelist>
|
|
<varlistentry>
|
|
<term>
|
|
<literal>16.03</literal>
|
|
</term>
|
|
<listitem>

|
<para>
|
|
The NixOS release, indicating the year and month in which it was
|
|

<para>
|
|
The number of commits in the Nixpkgs Git repository between the start of
|

|
This ensures that NixOS versions are monotonically increasing. It is
|
|
<literal>git</literal> when the current NixOS configuration was built
|
|
from a checkout of the Nixpkgs Git repository rather than from a NixOS
|
|
channel.
