You are of course correct, it runs under "sh"
I think that means I have to run it in a separate script file
I write it as (First_Hop subs with a.b.c.1)
if ! ping -c1 First_Hop >/dev/null 2>/dev/null
ifconfig em0 down && ifconfig em0 up
Save as /etc/pinger.sh
/etc/pinger.sh: Permission denied.
pfsense-p266ii:~# chmod 777 /etc/pinger.sh
chmod: /etc/pinger.sh: Read-only file system
Hmmmm I assume if it won't run here then crontab won't run it either?

The script I provided assumes the sh shell. Most shell scripts have
been historically written for the bourne shell. Before running the
script I sent you, try typing sh<enter> at the command line. Then,
run the line I sent your way.
Let me know how it works for you!
