# users

Use the `users` InSpec audit resource to look up all local users available on the system, and then test specific properties of those users. This resource does not return information about users that may be located on other systems, such as LDAP or Active Directory.

<br>

## Syntax

A `users` resource block declares a user name, and then one (or more) matchers:

    describe users.where(uid: 0).entries do
      it { should eq ['root'] }
      its('uids') { should eq [1234] }
      its('gids') { should eq [1234] }
    end

where

* `gid`, `group`, `groups`, `home`, `maxdays`, `mindays`, `shell`, `uid`, and `warndays` are valid matchers for this resource
* `where(uid: 0).entries` represents a filter that runs the test only against matching users

For example:

    describe users.where { username =~ /.*/ } do
      it { should exist }
    end

or:

    describe users.where { uid =~ /^S-1-5-[0-9-]+-501$/ } do
      it { should exist }
    end

<br>

## Examples

The following examples show how to use this InSpec audit resource.

### Use a regular expression to find users

    describe users.where { uid =~ /S\-1\-5\-21\-\d+\-\d+\-\d+\-500/ } do
      it { should exist }
    end

## Matchers

For a full list of available matchers, please visit our [matchers page](https://www.inspec.io/docs/reference/matchers/).

### exist

The `exist` matcher tests if the named user exists:

    it { should exist }

### gid

The `gid` matcher tests the group identifier:

    its('gid') { should eq 1234 } }

where `1234` represents the user identifier.

### group

The `group` matcher tests the group to which the user belongs:

    its('group') { should eq 'root' }

where `root` represents the group.

### groups

The `groups` matcher tests two (or more) groups to which the user belongs:

    its('groups') { should eq ['root', 'other']}

### home

The `home` matcher tests the home directory path for the user:

    its('home') { should eq '/root' }

### maxdays

The `maxdays` matcher tests the maximum number of days between password changes:

    its('maxdays') { should eq 99 }

where `99` represents the maximum number of days.

### mindays

The `mindays` matcher tests the minimum number of days between password changes:

    its('mindays') { should eq 0 }

where `0` represents the maximum number of days.

### shell

The `shell` matcher tests the path to the default shell for the user:

    its('shell') { should eq '/bin/bash' }

### uid

The `uid` matcher tests the user identifier:

    its('uid') { should eq 1234 } }

where `1234` represents the user identifier.

### warndays

The `warndays` matcher tests the number of days a user is warned before a password must be changed:

    its('warndays') { should eq 5 }

where `5` represents the number of days a user is warned.
