Alright, I feel like I have a pretty good basic knowledge of shell scripting, but this one is throwing me for a loop. I know I've seen something similar done with awk, but I couldn't find it with the search function.
I've grepped through my log file and get results like this:
Code:
--
/home/dir1/file-egress-filter-Remark : Stuff
/home/dir1/file-egress-filter-permit stuff
/home/dir1/file-egress-filter-permit other stuff
/home/dir1/file-egress-filter:permit more stuff
--
/home/dir1/other-egress-filter-Remark : Other
/home/dir1/other-egress-filter-permit other
/home/dir1/other-egress-filter-permit other others
/home/dir1/other-egress-filter:permit more other
--
This can continue on for few or many files. Notice that the last line of each has a colon ( as the last delimiter where as the others are a dash (-) and also that there is a : in the first line of each.
I want output like:
Code:
--
file-egress-filter
Remark : Stuff
permit stuff
permit other stuff
permit more stuff
--
other-egress-filter
Remark : Other
permit other
permit other others
permit more other
--
So, the stuff between each set of -- changes and I want to take the file name and use it as a header and then just print the stuff after the delimiter which is a dash for all but the last line.

tc-matchall
Match-all classifier in tc(8) Linux Match-all classifier in tc(8)NAME
matchall - traffic control filter that matches every packet
SYNOPSIS
tc filter ... matchall [ skip_sw | skip_hw ] [ action ACTION_SPEC ] [ classid CLASSID ]
DESCRIPTION
The matchall filter allows to classify every packet that flows on the port and run a action on it.
OPTIONS
action ACTION_SPEC
Apply an action from the generic actions framework on matching packets.
classid CLASSID
Push matching packets into the class identified by CLASSID.
skip_sw
Do not process filter by software. If hardware has no offload support for this filter, or TC offload is not enabled for the inter-
face, operation will fail.
skip_hw
Do not process filter by hardware.
EXAMPLES
To create ingress mirroring from port eth1 to port eth2:
tc qdisc add dev eth1 handle ffff: ingress
tc filter add dev eth1 parent ffff:
matchall skip_sw
action mirred egress mirror
dev eth2
The first command creats an ingress qdisc with handle ffff: on device eth1 where the second command attaches a matchall filters on it that
mirrors the packets to device eth2.
To create egress mirroring from port eth1 to port eth2:
tc qdisc add dev eth1 handle 1: root prio
tc filter add dev eth1 parent 1:
matchall skip_sw
action mirred egress mirror
dev eth2
The first command creats an egress qdisc with handle 1: that replaces the root qdisc on device eth1 where the second command attaches a
matchall filters on it that mirrors the packets to device eth2.
To sample one of every 100 packets flowing into interface eth0 to psample group 12:
tc qdisc add dev eth0 handle ffff: ingress
tc filter add dev eth0 parent ffff: matchall
action sample rate 100 group 12
