command to check disk I/O?


I'd like to know whether there exists a basic command to check disk I/O:
just currently there is disk I/Os or disk requests in system or not?

Because of in order to run or not some program according to the result:

if there exist disk I/Os or requests
put off running the program
run the program

Thanks in advance.

you would use the /sys folder for the individual file system

Thanks taxtropel

I see.
I probably can do that by checking the 9th column in /sys/block/sda/stat.
