rebalancing all coolers in an .mcool

[golobor]

I keep forgetting - how does one balance all coolers in a multi-cooler?
...is there any change cooler balance could be extended to assist users in this (common) task?

[nvictus]

for i in `cooler ls foo.mcool`; do
    cooler balance {options} $i;
done

any change cooler balance could be extended to assist users in this (common) task?

Since all cooler commands operate on single coolers and this task needs to be done sequentially anyway, cooler ls is really the concept to teach.

Extending commands to operate on mcools or larger collections opens up a lot of surface area and needs some thought. For now, probably better to better document or make this answer more visible.
