I'm afraid you can't make functions (like a normal programming does) in
cfengine.
To get closed to your expectation, you might need to create global variables
(bundle common) of the outputs of your commands/scripts then you could call it
up in every bundle. For instance;
body common control
{
bundlesequence => { "def","foo","bar" };
}
bundle common def
{
vars:
"global_result" string => execresult("/bin/ls /","noshell");
"global_split" slist => splitstring("$(global_result)"," ","100");
}
bundle agent foo
{
reports:
Yr2010::
"Found: $(def.global_result)";
}
bundle agent bar
{
vars:
"local_split" slist => { @(def.global_split) };
reports:
Yr2010::
"Found: $(local_split)";
}
Note that, you can only iterate common slist variable over local variables so
you need to pass a global slist variable to a local one in your bundle.
