Pardon my rant. Feel free to disregard this thread.

The output from these commands are on a freshly installed system.

One out of eight lines are actually disk filesystems. That is 88% 
garbage I didn't want to see.

$ mount -t ext3 ; mount -t ext4

$ man bash   for info on aliases and shell functions.

  Another alternative .... 

  alias drives='df -h -T -x tmpfs -x devtmpfs'
