# You probably want to add this to a cronjob, say every 10 minutes: |
| 6 |
# 0,10,20,30,40,50 * * * * /path/to/ihostchk.sh |
| 7 |
# And if you find yourself getting e-mails, use the following instead: |
| 8 |
# 0,10,20,30,40,50 * * * * /path/to/ihostchk.sh >/dev/null 2>&1 |
| 9 |
# NOTE: e-mails should only be sent if an error occurs, so the former is |
| 10 |
# the best choice for a cronjob. |
