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.

Currently I'm using the daily reboot script for asterisk and I was
just wondering what the following line actually does:
while /bin/ps ax | /bin/grep '[s]afe_asterisk' >/dev/null; do sleep 5; done
It is from this script which I'm running through crontab:
/usr/sbin/asterisk -rx "stop when convenient"
while /bin/ps ax | /bin/grep '[s]afe_asterisk' >/dev/null; do sleep 5; done
/sbin/rmmod wctdm
/sbin/modprobe wctdm
/usr/sbin/safe_asterisk
Yes I understand that daily reboot is unnecessary but until I find the
problem, this works for our needs. I'm wondering what that line does
because last night when the Cron job started running, it kept running
the job over and over until I got an out of memory error... as seen
below:
