sed调用shell自定义变量执行错误的问题

xiaoyawl

shell脚本

1. #!/bin/bash
   
2. 
   
3. IP=$(/sbin/ifconfig -a|grep inet|grep -v 127.0.0.1|grep -v 127.0.0.2|grep -v inet6|awk '{print $2}'|tr -d "addr:")
   
4. read -p "Please enter your WEB url1: " url11
   
5. echo ""
   
6. read -p "Please enter your WEB url2: " url12
   
7. echo ""
   
8. read -p "Please enter your WEB url3: " url13
   
9. echo ""
   
10. read -p "Please enter your WEB url4: " url14
    
11. echo ""
    
12. url21=http://www.abc.com/123.php?rows=10&iuplder=1&linktype=dl&passkey=
    
13. url22=http://www.abc.com/123.php?myrss=1&linktype=dl&uid=48&passkey=
    
14. url23=http://www.abc.com/456.php?&uid=
    
15. url24=http://www.abc.com/456.php?uid=
    
16. sed -i "3 s/$url21/$url11/" /root/.conf/comfig.yml
    
17. sed -i "22 s/$url22/$url12/" /root/.conf/comfig.yml
    
18. sed -i "34 s/$url23/$url13/" /root/.conf/comfig.yml
    
19. sed -i "54 s/$url24/$url14/" /root/.conf/comfig.yml
    
20. sleep 20
    
21. Pass=$(awk -F ':' '{print $2}' /root/.conf/auth)
    
22. sed -i "s/pass:&/pass:&$Pass/" /root/.conf/comfig.yml
    
23. chmod 644 /root/.conf/config.yml
    

复制代码

执行结果：

1. sed: -e expression #1, char 12: unknown option to `s'
   
2. sed: -e expression #1, char 13: unknown option to `s'
   
3. sed: -e expression #1, char 13: unknown option to `s'
   
4. sed: -e expression #1, char 13: unknown option to `s'
   
5. sed: can't read /root/.conf/comfig.yml: No such file or directory

     sed -i "3 s/$url21/$url11/"  ---> sed -i '3 s:'$url21':'$url11':'

   我按照你说的把/换成了: 加单引号了结果是

1. sed: -e expression #1, char 11: unknown option to `s'
   
2. sed: -e expression #1, char 12: unknown option to `s'
   
3. sed: -e expression #1, char 12: unknown option to `s'
   
4. sed: -e expression #1, char 44: unknown option to `s'
   
5. 123.sh: line 33: 3f152ca484201c4126a6aeeff8c95898fae0a94f:: command not found
   
6. 123.sh: line 33: :pass:: command not found

    使用一个不可能在变量出现的字符,

1. sed -i "3 s!$url21!$url11!"
