大佬们，Linux shell sed代码替换求助

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：

1. #!/bin/sh
   
2. 
   
3. a=$(ip address | grep ^[0-9] | awk -F: '{print $2}' | sed "s/ //g" | grep '^[e]' | grep -v "@" | grep -v "\.")
   
4. b=$(echo "$a" | wc -l)
   
5. rm -f /tmp/state/ethinfo
   
6. 
   
7. echo -n "[" > /tmp/state/ethinfo
   
8. 
   
9. for i in $(seq 1 $b)
   
10. do
    
11.         h=$(echo '{"name":' )
    
12.         c=$(echo "$a" | sed -n ${i}p)
    
13.         d=$(ethtool $c)
    
14. 
    
15.         e=$(echo "$d" | grep "Link detected" | awk -F: '{printf $2}' | sed 's/^[ \t]*//g')
    
16.         if [ $e = yes ]; then
    
17.                 l=1
    
18.         else
    
19.                 l=0
    
20.         fi
    
21. 
    
22.         f=$(echo "$d" | grep "Speed" | awk -F: '{printf $2}' | sed 's/^[ \t]*//g' | tr -d "Unknown!")
    
23.         [ -z "$f" ] && f=" - "
    
24. 
    
25.         g=$(echo "$d" | grep "Duplex" | awk -F: '{printf $2}' | sed 's/^[ \t]*//g')
    
26.         if [ "$g" == "Full" ]; then
    
27.                 x=1
    
28.         else
    
29.                 x=0
    
30.         fi
    
31. 
    
32.         echo -n "$h "$c", "status": $l, "speed": "$f", "duplex": $x}," >> /tmp/state/ethinfo
    
33. done
    
34. 
    
35. sed -i 's/.$//' /tmp/state/ethinfo
    
36. 
    
37. echo -n "]" >> /tmp/state/ethinfo
    
38. 
    
39. cat /tmp/state/ethinfo
