Can something similar be used for my
ifconfig_rl0_aliasN="inet 66.252.2.N netmask 255.255.255.255"
as well?
This is not as elegant, but may help in a similar way:
alia=-1;
while [ "$alia" -lt '123' ] ; do
alia=$(($alia+1)) ;
ips=$(($alia+4)) ;
echo "ifconfig_rl0_alias$alia=\"inet 66.252.2.$ips netmask
255.255.255.255\"" ;
done

What a gorgeous solution ;)
Thanks man!

Hey, I got a couple of hundred IPs, is there an easy way to add them
all to jail_box_ip="ip1,ip2,ip3" without making like the longest line

Like this?
jail_box_ip="66.252.2.4,\
66.252.2.5,\
66.252.2.6,\
Unfortunately that doesn't look too good.
Nor does:
export x=$(cat ips);export jail_ips=''; for ip in $x; do export
jail_ips="$jail_ips,$ip"; done; export jail_ips=$(echo $jail_ips | sed
s/,$/''/ | sed s/^,//);
Is there a more beautiful alternative?
/etc/rc.conf is just /bin/sh code. All you need to do is set
the variables -- usually by assigning a static string, but you
can use whatever constructs you want. Well - within reason. Making
something as critical as the system boot process depend on a bunch of
other files or processes is not a good idea on the whole.
You can include multi-line whitespace in the variables by using single
quotes:
jail_box_ip='66.252.2.4,
66.252.2.5,
66.252.2.6,
66.252.2.7'
Assuming that the init script that processes this data isn't phased
by the inclusion of a bit of whitespace.
Or you can generate the required numbers, assuming they are
consecutive:
jail_box_ip=$( jot -w "66.252.2.%d" -s "," 5 4 )
Cheers,
Matthew
