The "|" in egrep is an "or".
It problably make more sense to convert to
awk takes the same ERE as egrep, namely "[7-9][0-9]%|100%" but this operates on $5=column#5 only.
The main advantage is that it only prints the header (from NR=line#1) if needed.

Hi,
I am wondering if it's possible to link multiple patterns with egrep.
Here here is what I am doing :

tc-csum
Checksum action in tc(8) Linux Checksum action in tc(8)NAME
csum - checksum update action
SYNOPSIS
tc ... action csum UPDATE
UPDATE := TARGET [ UPDATE ]
TARGET := { ip4h | icmp | igmp | tcp | udp | udplite | sctp | SWEETS }
SWEETS := { and | or | + }
DESCRIPTION
The csum action triggers checksum recalculation of specified packet headers. It is commonly used to fix incorrect checksums after the pedit
action has modified the packet content.
OPTIONS
TARGET Specify which headers to update: IPv4 header (ip4h), ICMP header (icmp), IGMP header (igmp), TCP header (tcp), UDP header (udp),
UDPLite header (udplite) or SCTP header (sctp).
SWEETS These are merely syntactic sugar and ignored internally.
EXAMPLES
The following performs stateless NAT for incoming packets from 192.0.2.100 to new destination 198.51.100.1. Assuming these are UDP packets,
both IP and UDP checksums have to be recalculated:
# tc qdisc add dev eth0 ingress handle ffff:
# tc filter add dev eth0 prio 1 protocol ip parent ffff:
u32 match ip src 192.0.2.100/32 flowid :1
action pedit munge ip dst set 198.51.100.1 pipe
csum ip and udp
