[ubellavance]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 7.27.0
• Ruby:
• Distribution: RHEL8
• Module version: 2.0.0

How to reproduce (e.g Puppet code you use)

Trying to create a cronjob with the tilde, which tells cron to use a random valid number

       Randomization  of  the  execution  time within a range can be used.  A random number within a range specified as two numbers separated with a tilde is picked.  The specified range is inclusive.  For example, 6~15 for a 'minutes' entry picks a random minute within 6 to 15
       range.  The random number is picked when crontab file is parsed.  The first number must be less than or equal to the second one. You might omit one or both of the numbers specifying the range.  For example, ~ for a 'minutes' entry picks a random minute  within  0  to  59
       range.
