"Linux" process do not open too much, or the system will be stuck!

Running a mission today, probably like this.

Python task.py-s input/

The input folder has more than 200 files, such as 1.txt, 2.txt and so on, and task.py will read and do the operation sequentially.

I think it's not too slow. So I wrote a shell script.

Python task.py-s input/1.txt &-S Input/2.txt&-S Input/3.txt &...

And then it was tragic.

More than 200 processes start, the whole system is stuck! It's not moving at all!!!

Now think of the solution:

Ps-aux|grep python task.py

Then kill all related processes.

The key problem is that the system is unresponsive now and cannot input commands/(ㄒoㄒ)/~~
