Hi,
I am wondering how I can check the return value of all commands in a pipe such as
gzip -dc file.gz | sort -u > output.txt
If I run this sequence in bash and check $?, I get the return status from sort. But I want to know if the initial gzip failed.
Similarly for longer pipe chains,... (6 Replies)

tc-mirred
Mirror/redirect action in tc(8) Linux Mirror/redirect action in tc(8)NAME
mirred - mirror/redirect action
SYNOPSIS
tc ... action mirred DIRECTION ACTION [ index INDEX ] dev DEVICENAME
DIRECTION := { ingress | egress }
ACTION := { mirror | redirect }
DESCRIPTION
The mirred action allows packet mirroring (copying) or redirecting (stealing) the packet it receives. Mirroring is what is sometimes
referred to as Switch Port Analyzer (SPAN) and is commonly used to analyze and/or debug flows.
OPTIONS
ingress
egress Specify the direction in which the packet shall appear on the destination interface.
mirror
redirect
Define whether the packet should be copied (mirror) or moved (redirect) to the destination interface.
index INDEX
Assign a unique ID to this action instead of letting the kernel choose one automatically. INDEX is a 32bit unsigned integer greater
than zero.
dev DEVICENAME
Specify the network interface to redirect or mirror to.
EXAMPLES
Limit ingress bandwidth on eth0 to 1mbit/s, redirect exceeding traffic to lo for debugging purposes:
# tc qdisc add dev eth0 handle ffff: ingress
# tc filter add dev eth0 parent ffff: u32
match u32 0 0
action police rate 1mbit burst 100k conform-exceed pipe
action mirred egress redirect dev lo
Mirror all incoming ICMP packets on eth0 to a dummy interface for examination with e.g. tcpdump:
# ip link add dummy0 type dummy
# ip link set dummy0 up
# tc qdisc add dev eth0 handle ffff: ingress
# tc filter add dev eth0 parent ffff: protocol ip
u32 match ip protocol 1 0xff
action mirred egress mirror dev dummy0
Using an ifb interface, it is possible to send ingress traffic through an instance of sfq:
# modprobe ifb
# ip link set ifb0 up
# tc qdisc add dev ifb0 root sfq
# tc qdisc add dev eth0 handle ffff: ingress
# tc filter add dev eth0 parent ffff: u32
match u32 0 0
action mirred egress redirect dev ifb0
