Prototype: sort(list, mode)
Return type: slist
Description: Returns list sorted according to mode.
Lexicographical, integer, real, IP, and MAC address sorting is supported currently. The example below will show each sorting mode in action.
Note IPv6 addresses can not use uppercase hexadecimal characters
(A-Z) but must use lowercase (a-z) instead.
Arguments:
list:string, in the range:[a-zA-Z0-9_$(){}\[\].:]+mode: one oflexintrealIPipMACmac
Example:
body common control
{
bundlesequence => { test };
}
bundle agent test
{
