Pattern matching: operators and wildcards

Wildcards and operators can be used in many Tasks but also in Team rules, conditions and evaluators to define a set of objects, rather than naming a specific one.


Use a pattern such as LIKE 10.1.7.* instead of a fixed list of IP addresses as a Team Rule. This rule will not only be applied to all existing Agents whose IP address match the specified pattern: new Agents are automatically added to the list if their IP addresses match the pattern provided.

Add a condition with an expression using an operator in combination with a pattern: if the Fully Qualified Domain Name LIKE *RES.NL then execute this Module.



Stands for




larger/more than


smaller/less than


equal to or smaller/less than


equal to or larger/more than


larger/more than or smaller/less than (but not equal to)


matches a given pattern. If a value matches the pattern, the operator returns True; otherwise, it returns False.

Always use LIKE if the value contains a wildcard. For example, when setting a Team Rule based on an IP address, set the Operator LIKE and the value 10.1.7.*

LIKE ensures that the wildcard is interpreted as such. With other operators, the value is interpreted literally. (So the Team Rule in the above-mentioned example would never be met, because 10.1.7.* is not a valid IP addresses that can exist in any environment.)


does not match the pattern. If a value does not match the pattern, the operator returns True; otherwise, it returns False.

Wildcard characters

Wildcards can only be used in combination with the operators LIKE and NOT LIKE. Combinations of wildcard characters are allowed.


Stands for



Any single character

ba? matches bat, bad, bag, ba1, ba2, ...


Zero or more characters


Unix/Linux and Mac OS X Tasks: Zero or more occurrences of the previous character

a*a matches andromeda, aga, aa, a888a, a0a, ...


Unix/Linux and Mac OS X Tasks: * cannot be used on its own as a wildcard pattern matching expression – it must be preceded with another character, for example tre* matches tree (2 occurrences of e), tread (1 occurrence of e) and trough (0 occurrences of e).


Any single digit (0-9)

a#b matches a1b, a2b, ..., a9b but not aga, aka, ...


Excludes a pattern

a[!1-8] matches aa, ab, a9, ..., but not a1, a2, ...


Any single character in charlist

a[A-L] matches aa, ab, ... al but not am, an, ...


Any single character not in charlist

a[!A-L] matches am, an, ..., az but not aa, ab, ... al
