Question

if I had a txt file like this:

aBC$

abc

ABC

abc$

bAc!

How would I remove the lines where is doesn't have a symbol AND capital letter? I cannot delete them manually because I'm dealing with files more than a thousand lines. My wanted output would be:

aBC$

bAc!

I use emEditor and notepad++
