[Asterisk-Users] Daily Reboot Script for Asterisk Question

[Mojo with Horan & Company, LLC]

the while loop runs "ps ax" which shows all active processes. the text 
output is piped through grep looking for lines containing 
"[s]afe_asterisk".  Only these lines will be printed by grep. 
Basically, if the while loop gets any textual lines after grep is done, 
it considers the result true and proceeds with sleep 5.  if grepping for 
the text results in no output (asterisk isn't running) then the while 
loop is terminated and asterisk is restarted.  The loop is then began 
again, presumably.
