I am not sure this is correct. For example, this bundle...
bundle agent atest {
vars:
"mylist[a]" string => "1";
"mylist[b]" string => "2";
"mylist[c]" string => "3";
"mykeys" slist => getindices("mylist");
"myarray[$(mykeys)]" string => execresult("/bin/echo
say_$(mylist[$(mykeys)]) | grep $(mylist[$(mykeys)])","useshell");
reports:
Yr2010::
">>$(myarray[$(mykeys)])";
}
...will print out reports as I expect, and without the error messages
before. So clearly, I can iterate over a list as part of an lvar in an
expression.
$ cf-agent -KI -f ./testbundle.cf
R: >>say_1
R: >>say_2
R: >>say_3
There seems to be something particular output the output of 'ps' that is
somehow causing it to trip up...that being said I can always run without -I
(which is what I do anyway), and the errors are not displayed but the result
is OK.
