StopByName 

Shell execution according to the input string I find is the purpose of the corresponding process to kill

Such execution returns results for

 [root @ localhost new] # sh deploy1. Sh -m asfasfa 
The line: 26 

But if I find myself running program, this program is not running, but I still get to the unknown pid

 [root @ localhost new] # sh deploy1. Sh - M com test. Auto. Main. AutoMain 
The line: 26, 24685, 24686 
Deploy1. Sh: line 27: [: 24685: unary operator expected 

Execute the following command, you can see that my program is not running

 [root @ localhost new] # ps - ef | grep com. Test. Auto. Main. AutoMain | grep -v grep | awk '{print $2}' | awk -f "/" '{print $1} 
[root @ localhost new] # 

What is the cause?

I adjusted the code, I found, as long as the string from the specified outside will appear this problem
