Lot of times you want to check the disk rpm, especially on the servers to check if it is 7.2K or 10K or 15K rpm disk. How do you do this from linux terminal. Here it is :
sginfo -g /dev/<device>
Note that sginfo comes from sg3-utils.
Sometimes some simple one-liner function can save you a lot of time, like-
wps ()
{
rpm -q --whatprovides $(which $1 )
} # ---------- end of function wps ----------

For this tip, you would need to setup the rpm-shere repository. You can get the information here. Once you have done that you need to install the cdu package with the following command:
sudo yum install cdu
