在记事本++中如何查找与2“：”匹配的行

Question

I'd like to search/find lines containing "@" then 2 times ":"

A few examples :

www@xxx:yyy:zzz would match (it contains "@" then ":" then ":" again)
sample:help:new would not match (no "@")
fun@blue:turtle would not match (only 1 time ":")

Many thanks!

If you want to print the lines which has atleast one @ ,two : symbols then you could try the below regex.

^.*@.*:.*:.*$

If you want to print the lines which has exactly one @ symbol and two or more : symbols then you could try the below.

^[^@]*@[^@]*:[^@]*:[^@]*$
