why this command can't work?

The problem may be that the quotation marks should be ` rather than ',
i.e. you should use:

kill `cat /home/bro/bro.pid`;

rather than

> kill 'cat /home/bro/bro.pid';
> when i run this command,it says:
> kill:cat /home/bro/bro.pid no such pid

Does this solve the problem?
