Is there a way to define an empty list ?
I tried with the following code, and "ltwo" isn't expanded
body common control {
bundlesequence => { "test" };
}
bundle common g {
classes:
"all" expression => "any";
}
bundle agent test {
vars:
sunos_5_10::
"lone" slist => {};
"ltwo" slist => { "three", "four", "five" };
ubuntu::
"ltwo" slist => {};
"lone" slist => { "one", "two", "three" };
any::
"x" slist => { "@{lone}", "@{ltwo}" };
reports:
all::
"${x}";
}
