I have multiple servers of Linux, where I need to test the performance of my program, here I want to output the system state when running programs. In script of linux, I use following to output:

top -b -d 5 > System.txt
iostat -d 8 > IO.txt

But unfortunately, only the system.txt can be produced, but there is no the IO.txt file, so that need to add some thing in script to make these two file exist together?

Use iostat command like this :- iostat -d 8 1 > IO.txt.

In this 1 means the limit, how many time do you want to run the command get the result.
