Increase speed of a particular job
If I am copying hundreds of files from one folder to another using the terminal, is there any way I can add an argument to use n number of CPUs for this particular job?

What makes you think that the job saturates a cpu?
First gather and evaluate the metric graphs of iowait, load, iops, etc
Then you can know the current bottleneck and evaluate options.You must always face the curtain with a bow.

This command is most likely io bound, not cpu bound.
So: no.You must always face the curtain with a bow.

is this the exact command that is giving you trouble?
what do you think it does?
i'm not sure it's good or even valid syntax.
shouldn't you be using the -r option instead?
did you readCode:man cp
this might have an impact on performance.
anyhow, the bottleneck is the underlying storage hardware's i/o capabilities, NOT the cpu.
