大佬们，Linux shell sed代码替换求助
[i=s] 本帖最后由 smdx 于 2022-3-11 10:37 编辑 [/i]各位大佬好，Linux shell sed代码替换求助，请问如何用sed命令替换代码？
想实现把代码的
a=$(ip address | grep ^[0-9] | awk -F: '{print $2}' | sed "s/ //g" | grep '^[e]' | grep -v "@" | grep -v "\.")
替换成
a=$(ip address | grep ^[0-9] | awk -F: '{print $2}' | sed "s/ //g" | grep '^eth' | awk -F"@" '{print $1}')
命令用于GitHub Actions云编译openwrt固件sh脚本，请问要怎么做？谢谢
ethinfo原代码：[code]#!/bin/sh
a=$(ip address | grep ^[0-9] | awk -F: '{print $2}' | sed "s/ //g" | grep '^[e]' | grep -v "@" | grep -v "\.")
b=$(echo "$a" | wc -l)
rm -f /tmp/state/ethinfo
echo -n "[" > /tmp/state/ethinfo
for i in $(seq 1 $b)
do
h=$(echo '{"name":' )
c=$(echo "$a" | sed -n ${i}p)
d=$(ethtool $c)
e=$(echo "$d" | grep "Link detected" | awk -F: '{printf $2}' | sed 's/^[ \t]*//g')
if [ $e = yes ]; then
l=1
else
l=0
fi
f=$(echo "$d" | grep "Speed" | awk -F: '{printf $2}' | sed 's/^[ \t]*//g' | tr -d "Unknown!")
[ -z "$f" ] && f=" - "
g=$(echo "$d" | grep "Duplex" | awk -F: '{printf $2}' | sed 's/^[ \t]*//g')
if [ "$g" == "Full" ]; then
x=1
else
x=0
fi
echo -n "$h \"$c\", \"status\": $l, \"speed\": \"$f\", \"duplex\": $x}," >> /tmp/state/ethinfo
done
sed -i 's/.$//' /tmp/state/ethinfo
echo -n "]" >> /tmp/state/ethinfo
cat /tmp/state/ethinfo
