我试过（在vim里面）

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

它不起作用。

有什么建议么？

Answer 1

For some reason vim wants \r in the replacement, so if you change your substitution to:

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

it will work.

If you don't mind the extra whitespace, this will work in sed:

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

Answer 2

如果多余的空格很烦人，您可以使用GNU awk：

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