28楼的我早上测试过了,如果还有问题,请贴出你的初始文本,
执行代码,错误提示.

这个文本,我这边这段代码执行没问题的,前面算变量m的sed代码应该
有些特性在你的系统里不支持,导致m为空,然后s命令就会有问题。

1. 
   
2. [root@lnx-rh6-x64 zzz]# m=`sed -nr '0,/0x0000000a/{//s/.*= "(([0-9A-Fa-f]{2}:){3}).*/\1/p}' mac.txt`;echo $m
   
3. D8:49:0B:
   
4. [root@lnx-rh6-x64 zzz]# sed "s//22/" mac.txt
   
5. sed: -e expression #1, char 0: no previous regular expression
   
6. [root@lnx-rh6-x64 zzz]#

复制代码

改成这样严谨一点，但你的系统估计还是不行，也许不支持//

1. m=`sed -nr '0,/0x0000000a/{//s/.*= "(([0-9A-Fa-f]{2}:){3}).*/\1/p}' mac.txt`;[ -n "$m" ]&&sed "s/$m/22:33:44:/" mac.txt
   
2. obj.id = "0x00000007" ; obj.value = "021VQR3GE2161594";
   
3. obj.id = "0x00000008" ; obj.value = "631458q5e2";
   
4. obj.id = "0x00000009" ; obj.value = "";
   
5. obj.id = "0x0000000a" ; obj.value = "22:33:44:3D:74:2D";
   
6. obj.id = "0x0000000b" ; obj.value = "65:D9:80:13:00:0B";
   
7. obj.id = "0x00000022" ; obj.value = "";
   
8. obj.id = "0x00000023" ; obj.value = "";
   
9. obj.id = "0x00000024" ; obj.value = "";
   
10. obj.id = "0x0000000c" ; obj.value = "22:33:44:3D:74:2E";
    
11. obj.id = "0x0000000d" ; obj.value = "22:33:44:3D:74:2F";
    
12. obj.id = "0x0000000e" ; obj.value = "22:33:44:3D:74:30";
    
13. obj.id = "0x00000013" ; obj.value = "22:33:44:3D:74:35";
    
14. obj.id = "0x00000016" ; obj.value = "738011635059";

可以试一下这段代码，我去掉了//，也许可以。

1. m=`sed -nr '/0x0000000a/{s/.*= "(([0-9A-Fa-f]{2}:){3}).*/\1/p;q}' mac.txt`;[ -n "$m" ]&&sed "s/$m/22:33:44:/" mac.txt
   
2. obj.id = "0x00000007" ; obj.value = "021VQR3GE2161594";
   
3. obj.id = "0x00000008" ; obj.value = "631458q5e2";
   
4. obj.id = "0x00000009" ; obj.value = "";
   
5. obj.id = "0x0000000a" ; obj.value = "22:33:44:3D:74:2D";
   
6. obj.id = "0x0000000b" ; obj.value = "65:D9:80:13:00:0B";
   
7. obj.id = "0x00000022" ; obj.value = "";
   
8. obj.id = "0x00000023" ; obj.value = "";
   
9. obj.id = "0x00000024" ; obj.value = "";
   
10. obj.id = "0x0000000c" ; obj.value = "22:33:44:3D:74:2E";
