Re: [Condor-users] Dynamic Custom Resources in Condor

Ben,

Your script should output ClassAd attribute assignments in its standard 
output.  For example, if you want to have your script set a ClassAd 
attribute named "Likes" to the value "bread" and an attribute "Quantity" 
to 3, you would make your script generate the following output:

Likes = "bread"
Quantity = 3
