I'd forgotten all about that syntax as my more intermediate-to-advanced Perl has gotten a bit rusty. I'm glad to know that works with libpcre. Thanks for the tip!

Without it, a dot does not match when the current position is at a newline. This option is equivalent to Perl's /s option, and it can be changed within a pattern by a (?s) option setting. A negative class such as [^a] always matches newline characters, independent of the setting of this option. So the example below works as expected (see the change in the "port2" regex). Best regards, --Diego body common control { bundlesequence => { "test" }; } bundle common agent { classes: "all" expression => "any"; } bundle agent test { vars: "reg" string => "OpenSSH"; "str1" string => "SSH-OpenSSH-4.3"; "str2" string => "SSH-OpenSSH-4.3 newline"; classes: "port1" expression => regcmp(".*${reg}.*","${str1}"); "port2" expression => regcmp("(?s).*${reg}.*","${str2}"); # Both DO match reports: port1:: "Port1 match!"; !port1:: "No port1 match!"; port2:: "Port2 match!"; !port2:: "No port2 match!"; } -----Original Message----- From: help-cfengine-boun...@cfengine.org [mailto:help-cfengine-boun...@cfengine.org] On Behalf Of Justin Lloyd Sent: Wednesday, February 17, 2010 3:01 PM To: nwat...@symcor.com; Mark Burgess Cc: Lebel, Marco; help-cfengine@cfengine.org Subject: RE: regcmp help Theoretically speaking, this would probably only work with a two-line string, correct?

It's a bit painful compared with m// so I still wish for that :) Still thanks for the clarification and your patience with my stubbornness.
