Re: [HTCondor-users] $INT conversion failing in submit file

Thanks Todd!

I like the use of condor_status with -constraint to evaluate the expressions. Works like a champ.

Cheers,
Mike

Just use your requirements expression as what you give to -constraint, and condor_status will limit (constrain) the output to just the machines where the expression evaluates to True.  Be careful to escape quotation marks so cmd.exe (on windows) or bash (on Linux/Mac) doesn't mess things up.
