Using while to run a command number of times + UNIX

Hi Friends,

We can use while to run a command multiple times with a time difference of n seconds.

[root@abc /]# while true
> do sleep 10
> df -h
> done

===========


the output of df command is coming after every ten seconds. these can be used when monitoring the size of file system while reducing it using find or rm.
