Re: method to check for package installation

[Christian Pearce]

Graham,

I have been doing this for years.

control:
 
    logwatch_rev     = ( "5.1-1" )
    logwatch_package = ( "logwatch-$(logwatch_rev).noarch.rpm" )

groups:
    # Test to see if logwatch is installed.
    logwatch_installed = ( ReturnsZero(${rpm} -q --quiet logwatch) )
 
    # Test to see if logwatch is upgraded to the latest version.
    logwatch_upgraded = ( ReturnsZero(${rpm} -q --quiet
logwatch-${logwatch_rev}) )
