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 ever?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 -- Dr Matthew J Seaman MA, D.Phil. 7 Priory Courtyard Flat 3 PGP: http://www.infracaninophile.co.uk/pgpkey Ramsgate Kent, CT11 9PW
