Use command lines to test the CPU load

I accidentally saw an article on the 51 homepage about "creating CPU load or pressure through command line". I thought it was good to record it first and make notes for future use!

It is very simple, just a command:

# Cat/dev/urandom | md5sum

Then through top observation, the CPU value is really high, indicating that the test is successful!

Graph and truth ^_^
