[%CFEngine_function_prototype(list, regex)%]

Description: Returns whether the [anchored][anchored] regular expression regex matches any item in list.

[%CFEngine_function_attributes(list, regex)%]

Example:

[%CFEngine_include_snippet(reglist.cf, #+begin_src cfengine3, .*end_src)%]

Output:

[%CFEngine_include_snippet(reglist.cf, #+begin_src\s+example_output\s, .end_src)%]

In the example above, the IP address in $(sys.ipv4[eth0]) must be escaped, so that the (.) characters in the IP address are not interpreted as the regular expression “match any” characters.
