# crontab
|
|
|
|
Use the `crontab` Chef InSpec audit resource to test the crontab entries for a particular user on the system. It recognizes special time strings (@yearly, @weekly, etc).
|
|
|
|

|
|
|
|
## Availability
|
|
|
|
### Installation
|
|
|
|
This resource is distributed along with Chef InSpec itself. You can use it automatically.
|
|
|
|
### Version
|
|
|
|
This resource first became available in v1.15.0 of InSpec.
|
|
|
|
## Syntax
|
|
|
|
A `crontab` resource block declares a user (which defaults to the current user, if not specified), and then the details to be tested, such as the schedule elements for each crontab entry or the commands itself:
|
|
|
|
describe crontab do
|
|
its('commands') { should include '/some/scheduled/task.sh' }
|
|
end
|
|
|
|
The path to the system crontab can also be supplied via:
|
|
|
|
describe crontab(path: '/etc/cron.d/some_crontab') do
|
|
its('commands') { should include '/path/to/some/script' }
|
|
end
|
|
|
|
Note that only the path or the user (and not both) should be supplied as arguments to the resource.
|

## Examples
|
|
|
|
The following examples show how to use this Chef InSpec audit resource.
|
|
|
|
### Test that root's crontab has a particular command
|
|
|
|
describe crontab('root') do
|
|
its('commands') { should include '/path/to/some/script' }
|
|
end
|
|
|
|
### Test that myuser's crontab entry for command '/home/myuser/build.sh' runs every minute
|
|
|
|
describe crontab('myuser').commands('/home/myuser/build.sh') do
|
|
its('hours') { should cmp '*' }
|
|
its('minutes') { should cmp '*' }
|
|
end
|
|
|
|
### Test that the logged-in user's crontab has no tasks set to run on every hour and every minute
|
|
|
|
```ruby
|
|
describe crontab.where({'hour' => '*', 'minute' => '*'}) do
|
|
its('entries.length') { should cmp '0' }
|
|
end
|
|
```
|
|
|
|
### Test that the logged-in user's crontab contains a single command that matches a pattern
|
|
|
|
```ruby
|
|
describe crontab.where { command =~ /a partial command string/ } do
|
|
its('entries.length') { should cmp 1 }
|
|
end
|
|
```
|
|
|
|
### Test a special time string (i.e., @yearly /root/annual_report.sh)
|
|
|
|
describe crontab.commands('/root/annual_report.sh') do
|
|
its('hours') { should cmp '0' }
|
|
its('minutes') { should cmp '0' }
|
|
its('days') { should cmp '1' }
|
|
its('months') { should cmp '1' }
|
|
end
|
|
|
|
### Test @reboot case
|
|
|
|
describe crontab.commands('/root/reboot.sh') do
|
|
its('hours') { should cmp '-1' }
|
|
its('minutes') { should cmp '-1' }
|
|
end
|
|
|
|
<br>
|
|
|
|
## Property Examples
|
|
|
|
|
|
### Test a special time string
|
|
|
|
describe crontab do
|
|
its('minutes') { should cmp '0' }
|
|
its('hours') { should cmp '0' }
|
|
its('days') { should cmp '1' }
|
|
its('weekdays') { should cmp '1' }
|
|
its('user') { should include 'username'}
|
|
its('commands') { should include '/some/scheduled/task.sh' }
|
|
end
|
|
|
|
Chef InSpec will automatically interpret crontab-supported special time strings. For example, a crontab entry set to run `@yearly` can be tested as if the entry was manually configured to run on January 1, 12 AM.
