能在awk中怎么实现类似grep -o的功能吗

kknddd

如题

kknddd

就是要取得$1 和 $2中匹配正则的部分

寂寞烈火

try:

1. 
   
2. 
   
3. /home/lee#echo "abc ccd \nccc abc\njjj abc sdf"
   
4. abc ccd
   
5. ccc abc
   
6. jjj abc sdf
   
7. /home/lee#echo "abc ccd \nccc abc\njjj abc sdf"|grep -o '\<abc\>'
   
8. abc
   
9. abc
   
10. abc
    
11. /home/lee#echo "abc ccd \nccc abc\njjj abc sdf"|\
    
12. > awk '{for(i=1;i<=NF;i++)if($i~/\<abc\>/)print $i}'
    
13. abc
    
14. abc
    
15. abc
