Is there any command like nice so that I can run a command with a cpu

Short answer: no. You mean the app uses e.g. max 50% and if nothing
else is running the CPU is then 50% idle? There was a long thread on
OpenBSD (where people discuss kernel internals) that concluded that UNIX
has never had a scheduler that could do this.
What problem are you trying to solve where you think that this is the
answer?
The problem is that I'm using a laptop but somehow (I don't know
exactly why) recently when I run some cpu-intensive and time consuming
programs it caused the cpu too hot and an automatic shutdown is
resulted. I want to keep the CPU usage low for those programs to
avoid the forced shutdown.
In the mean while I'm also looking for an external CPU cooler. :)
