Question

使用桑达通过印刷替换模式，我想取代这个长线：

成这样：

http://download.lenovo.com/UserFiles/Driver/en/Downloads%20and%20Drivers/Z570/Win%207%20Update/IN1AUD25WW5.exe 
http://download.lenovo.com/UserFiles/Driver/en/Downloads%20and%20Drivers/Z570/Win7/IN2VDO61WW6.exe 

我试过（里面VIM ）

:%s#http://#\nhttp://#g 

它不起作用。

有什么建议吗？

Answer 1

出于某种原因vim希望在更换\r，因此，如果您更改替换到：

:%s#http://#\r&#g 

它会奏效。

如果你不介意额外的空白，这将在sed工作：

sed 's#http://#\n&#g' infile 

Answer 2

如果额外的空格是烦人，你可以使用GNU awk：

awk -F "http" '{ for (i=2; i<=NF; i++) print FS $i }' file.txt
