[GE users] Querying available slots with a resource string

Daniel,

Looks like the one-line script only shows the full number of slots that fit that description, not the slots available for running.  Is that correct?  I wanted to see how many are open.

Thanks,

Brad

Brad,

Reuti sent me a cleaner way to write the script:

qselect -l resource=value | xargs qconf -sq | awk ' /^slots/ { sum+=$2
 } 
END { print sum } '
