Replace using VIM, reuse part of the search pattern
參考：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 文件裏 test_12 test_2323
等test_後面帶數字的字符串，後面加一個x
變成test_12x test_2323x
%s/\(test_\d\+\)/\0x/g
註意這裏括號和+號都要加轉義

.net中建立目錄的問題(未找到路徑X的一部分|Could not find a part of the path)
