Re: Confusion with Variables and Groups

[Brendan Strejcek]

This works fine for me:

    $ cat test.cf 
    #!/usr/sbin/cfagent -qKf
    
    classes:
        testClass = ( linux )
    control:
        actionsequence = ( shellcommands )
        testClass:: testVar = ( junk )
    shellcommands:
        "/bin/echo testVar is ${testVar}"
    $ ./test.cf 
    cfengine::/bin/echo testV: testVar is junk
    $ 

I think that's a simple case of what you want.
