Replace using VIM, reuse part of the search pattern

参考：https://unix.stackexchange.com/questions/35206/replace-using-vim-reuse-part-of-the-search-pattern

 

 

\0 is the whole match. To use only part of it you need to set it like this and use \1

.s/(\([0-9]*\))/{\1}/

 

 

比如想把  文件里   test_12 test_2323  

等test_后面带数字的字符串，后面加一个x

变成test_12x   test_2323x

 

%s/\(test_\d\+\)/\0x/g

 

注意这里括号和+号都要加转义
