I set up a loop to print the last value of the "193 Load_Cycle_Count"
line from command "smartctl -d ata -a /dev/sda" once a minute this
morning.  I let it run all day, and after eight hours it never changed
from 328146.  I shutdown (hibernated) the system and resumed a bit later
in my home office.  The loop (which just resumed right along with
everything else) now prints a constant value of 328150 once a minute.

FWIW, the loop looks like:

  for whoCares in /usr/bin/*; do   # easy way to loop for a few days
    sudo smartctl -d ata -a /dev/sda | egrep '^[ \t]*193' | awk '{print

$NF;}'; sleep 60; done

The pedants are in:-)

# Thos loops for ever
while :
  do sudo smartctl -d ata -a /dev/sda | egrep '^[ \t]*193' \
	| awk '{print $NF;}';
  sleep 1m
  done

The grep and awk can be combined more elegantly too, but I'll leave that for the next pedant:-)

And sudo could be relocated to advantage....

The professor (insert big, big grin and wink here) answers:
Didn't want it to loop forever, just a day or two.  There are 2800+
files in /usr/bin, so 1440 minutes/day * 2 = 2880.  It works and it's
utterly trivial.  Also, this was a "quick and dirty" loop. I'm
interested in the numbers.  Is Fedora in fact stressing our disks?  How

does this compare to other OSes? Etc., etc.
