top is broken in Linux

[kkonstantine]

There's a stray comma that does not allow top to run on certain linux distros for all the services.
Also a check for empty pid needs to be added.

I imagine that there will be better ways but I have solved with these lines:

top_pid=echo $pids| sed 's/.$//g'
top -p "$top_pid"

Hi @vthot4, thanks so much for checking this out and suggesting a fix!
Allow me to encourage you to go ahead and directly issue a PR next time you have a similar suggestion. All of us will be thrilled! :)

Since the above had a minor issue of not catching multiple commas (the original bug could produce ,,,,, as well) I went ahead and issued a different patch which is also pretty brief.

Feel free to check it out and even try it from here: #45
