Hi Rajat

My version doesn't have "bal", does that mean it is not the most recent
version
from github? (our system administrator installed it and may have missed
that detail).

Is there a version string to look for?

$ starcluster bal mycluster -m 10 -n 2
StarCluster - (http://web.mit.edu/starcluster)
Software Tools for Academics and Researchers (STAR)
Please submit bug reports to starcluster_at_mit.edu

Error: invalid command 'bal'


$ starcluster --version
StarCluster - (http://web.mit.edu/starcluster)
Software Tools for Academics and Researchers (STAR)
Please submit bug reports to starcluster_at_mit.edu

0.91.2


-A
