求助！提取文件指定文本替换到文件中指定地方[已解决]

xiao_244

有一个1.ＴＸＴ文件：
obj.id = "0x00000005" ; obj.value = "08:AC:86:1E:98:43";
obj.id = "0x00000006" ; obj.value = "08:AC:86:1E:98:46";
中间还有一些行
obj.id = "0x00000019" ; obj.value = "";
obj.id = "0x00000020" ; obj.value = "08:AC:86:1E:98:21";
obj.id = "0x00000021" ; obj.value = "hore"
就是把0x0000005那一行的"08:AC:86:1E:98:43"去掉冒号成08AC861E9843再到前面加5个不变的数字12345成1234508AC861E9843替换0x0000019那行的obj.value = ""成obj.value = "1234508AC861E9843"
最后成：
obj.id = "0x00000005" ; obj.value = "08:AC:86:1E:98:43";
obj.id = "0x00000006" ; obj.value = "08:AC:86:1E:98:46";
obj.id = "0x00000019" ; obj.value = "1234508AC861E9843";
obj.id = "0x00000020" ; obj.value = "08:AC:86:1E:98:21";

不知道大家能看懂不!!!!
求大侠帮忙，　我每个都用ＶＩ手动改，太累了
sed grep 都行　awk用不了~！

没看出规律, 目测象 MAC地址.

    是每次替换都是00005和00019这两行吗？ 另外添加的数字是固定的吗？

我先把固定的情况写上(写的有点儿麻烦，希望高手改进)

1. 
   
2. sed -f replace_line_from_another_line.sed 1.txt
   
3. cat replace_line_from_another_line.sed
   
4. /00005/{
   
5.     h
   
6.     s/.*obj.value.*\"\(.*\)\".*/\1/
   
7.     s/://g
   
8.     s/.*/123456&/
   
9.     x
   
10. }
    
11. /00019/{
    
12.     G
    
13.     s/\"\";\n\(.*\)/\"\1\";/
    
14. }
    
15.

只会awk。。。学习sed。。。

1. awk 'BEGIN{FS=OFS="\""}{if($2=="0x00000005"){value=$4;gsub(/:/,"",value)};if($4=="")$4="123456"value;print $0}' urfile

1. awk '/0x00000005/{a=$NF}/0x00000019/{gsub(/:/,"",a);sub(/"/,"",a);$NF="\"123456"a}{print $0}'

中间三点的意思是还有很多这样的行，0x0000019也不是最后一行，命令运行之后结果和我想的不一样，帮忙改一下~！回复 3# seesea2517
