Operators for use in auto-enroll rules

You can use the following operators to write selectors for auto-enroll rules.

Comparison operators

Comparison operators are binary operators that take the following form:

{expression 1} {operator} {expression 2}

Table 1. Comparison operators
Operator	Alternative spellings	Description
`=`	`==`, `EQ`, `eq`	Tests if the property value is equal to the provided value.
`!=`	`NE`, `ne`	Tests if the property value is not equal to the provided value.
`<=`	`LE`, `le`	Tests if the property value is less than or equal to the provided value.
`<`	`LT`, `lt`	Tests if the property value is less than the provided value.
`>=`	`GE`, `ge`	Tests if the property value is greater than or equal to the provided value.
`>`	`GT`, `gt`	Tests if the property value is greater than the provided value.
`LIKE`	`like`	Tests if the property value matches a wildcard expression.
`REGEX`	`regex`	Tests if the property value matches a Rust-style regular expression.

Logical operators

Logical operators can be unary or binary.

Table 2. Logical operators
Operator	Alternative spellings	Description
`NOT`		Inverts (negates) the operators or expressions. Examples: `NOT property = value` which is equal to `property != value` or `NOT (property = value)` `property NOT LIKE value`
`AND`	`&&`, `&`	Pairs of sub-expressions connected using this operator must both evaluate to true for the full expression to be true.
`OR`	`\|\|`, `\|`	At least one of the sub-expressions connected using this operator must evaluate to true for the full expression to be true.
`IN`		The expression is true if the property is equal to one of a list of values. Example: `hostname IN rhel01, rhel02, rhel03` or `hostname IN (rhel01, rhel02, rhel03)`
`IS`		Checks the property for existence or presence of value: `EMPTY` If the property is empty. `NONE` True if the property doesn’t exist. You can use existence checks only for optional properties. `NULL` Alternative spelling for `NONE`. `SOME` True if the property exists. You can use existence checks only for optional properties. Examples: `enroll-time IS NONE` `enroll-time IS SOME`
`HAS`		True if the property exists. Example: `HAS enroll-time`. Equivalent to `enroll-time IS SOME` or `NOT (enroll-time is NONE)`
