Regular expression question

line !~ /(^#)|(^[\s\t]*$)/

Is supposed to filter empty lines and lines commented by “#” symbol at
the beginning.
Separately the both patterns work but with “|” operation it doesn’t
filter. What I missed?

I don’t master regex … but it seems you haven’t to put a backslash
before |
