# cat A
a
x
d

# cat B
EXPORT TO 'D:\test\org.ixf' OF IXF MESSAGES 'D:\test\org.msg' SELECT * FROM org;
EXPORT TO 'D:\test\org.ixf' OF IXF MESSAGES 'D:\test\org.msg' SELECT * FROM org;
EXPORT TO 'D:\test\org.ixf' OF IXF MESSAGES 'D:\test\org.msg' SELECT * FROM org;

怎么样实现这个呢？

EXPORT TO 'D:\test\a.ixf' OF IXF MESSAGES 'D:\test\a.msg' SELECT * FROM a;
EXPORT TO 'D:\test\x.ixf' OF IXF MESSAGES 'D:\test\x.msg' SELECT * FROM x;
EXPORT TO 'D:\test\d.ixf' OF IXF MESSAGES 'D:\test\d.msg' SELECT * FROM d;

方法1

paste A B | awk '{gsub(/org/,$1);$1="";print}'

方法2

 
    
     
     
  1. [root@localhost test]# cat bb.sh  
    2.  
     
  2. #!/bin/bash 
    3.  
     
  3. count=0 
    4.  
     
  4. for line in `cat A` 
    5.  
     
  5.  do 
    6.  
     
  6.    ((count++)) 
    7.  
     
  7.    sed -i "$count s/org/$line/g" B 
    8.  
     
  8. done 
    9.  
     
  9. [root@localhost test]# cat B 
    10.  
     
  10.  EXPORT TO 'D:\test\a.ixf' OF IXF MESSAGES 'D:\test\a.msg' SELECT * FROM a;
     EXPORT TO 'D:\test\b.ixf' OF IXF MESSAGES 'D:\test\b.msg' SELECT * FROM b;
     EXPORT TO 'D:\test\c.ixf' OF IXF MESSAGES 'D:\test\c.msg' SELECT * FROM c;

awk '{getline i <"A";gsub("org",i,$0)}1' B
