Hi Qi,
I wrote a script and this would save a good amount of time in scaled configuration
Script is as below
date
fdbshow -c
date
fdbshow | grep Total
date
Output: -c takes 8 seconds whereas with grep the time taken is 14 seconds.

In some scenarios it almost halves the time taken. On another note most of the options could be replaced by simple grep. The point of having them is performance as well as ease of use to the user. Most other operating systems do have these options and hence it makes beneficial to add this

I am wondering why it is so slow to grep. The only difference is collecting and printing a table. Is tabulate the slowest procedure?

Yes. Tabulate appears to be the bottleneck especially with bulk configurations. I prefer having the count option as is.
Added validation for different options Added new tests to validate error inputs
