Top Forums Shell Programming and Scripting awk : Filter a set of data to parse header line and last field of multiple same match. Post 302764679 by Scrutinizer on Thursday 31st of January 2013 06:25:29 PM

Hi, s/\n.* / :: /p means replace everything in the line buffer between the first linefeed and the last space with " :: " and print the result.

So for the first match the line buffer will contain the following after the 3 N-operations:
Code:
PKG= P8SDB     :: VGS = vgP8SOra vgP8SDB1 vgP8S001 vgP8S007 vgP8S003 vgP8S004 vgP8SOlog \nPKG= P8SDB    disks:                    \n-----------------------------------------------------------------------------------------------\n/dev/rdisk/disk7777   xx  00   00  xxxx  07:67  xxxx 00060110

so
\nPKG= P8SDB disks: \n-----------------------------------------------------------------------------------------------\n/dev/rdisk/disk7777 xx 00 00 xxxx 07:67 xxxx
will get replaced.. (\n is representation of the linefeed in this example)

NAME
agr -- link aggregation pseudo network interface driver SYNOPSIS
pseudo-device agr DESCRIPTION
The agr driver provides link aggregation functionality (a.k.a. L2 trunking or bonding). It supports the IEEE 802.3ad Link Aggregation Control Protocol (LACP) and the Marker Protocol. The agr driver supports the following link specific flags for ifconfig(8): link0 Use the round-robin distribution algorithm. Don't use it unless you're really sure, because it violates the frame ordering rule. -link0 Use the default distribution algorithm, which is based on the hash of DA/SA, TCI, and, if available, some upper layer protocol infor- mation like ip(4) DA/SA. link1 Disable LACP. Prevents any LACP or Marker messaging which leaves the ports in the default static configuration. Set this prior to adding ports. EXAMPLES
Create an agr interface, agr0, and attach re0 and re1 to it. In other words, aggregate re0 and re1 so that they can be used as a single interface, agr0. The physical interfaces which are attached to the agr interface must not have any IP addresses, neither IPv4 nor IPv6. ifconfig re0 inet xxx.xxx.xxx.xxx delete ifconfig re0 inet6 fe80::xxxx:xxxx:xxxx:xxxx delete ifconfig re1 inet xxx.xxx.xxx.xxx delete ifconfig re1 inet6 fe80::xxxx:xxxx:xxxx:xxxx delete ifconfig agr0 create ifconfig agr0 agrport re0 ifconfig agr0 agrport re1 Destroy an interface created in the above example. ifconfig agr0 -agrport re0 ifconfig agr0 -agrport re1 ifconfig agr0 destroy SEE ALSO
ifconfig(8) STANDARDS
IEEE 802.3ad Aggregation of Multiple Link Segments HISTORY
The agr driver first appeared in NetBSD 4.0. AUTHORS
The agr driver was written by YAMAMOTO Takashi. BUGS
There is no way to configure LACP administrative variables, including system and port priorities. The current implementation of the agr driver always performs active-mode LACP and uses 0x8000 as system and port priorities. The agr driver uses the MAC address of the first-added physical interface as the MAC address of the agr interface itself. Thus, removing the physical interface and using it for another purpose can result in non-unique MAC addresses. The current implementation of the agr driver doesn't prevent unsafe operations like some ioctls against underlying physical interfaces. Such operations can result in unexpected behaviors, and are strongly discouraged. There is no way to configure agr interfaces without attaching physical interfaces. Physical interfaces being added to the agr interface shouldn't have any addresses except for link level address. Otherwise, the attempt will fail with EBUSY. Note that it includes an automatically assigned IPv6 link-local address. BSD
