> Currently if you have a table foo with 5 rows in it, you can run this command:
> {code}
> hbase(main):001:0> x = count 'foo'
> 3100 row(s) in 0.7030 seconds
> hbase(main):001:0> x
> nil
> {code}
> Ideally, the 'x' variable should be 5. so something like this coudl be done:
> {code}
> Kernel.exit 127 if x != 5
> {code}
> This is useful for having scripts that can check a condition and act.
