How to specify the period "." character when doing a gsub

All-

Plz advise how to specify the period “.” character when doing a gsub.

eg, doing this:

some_object.gsub(/123.456/, “some_string”)

seems to treat the “.” as a wildcard of some kind. I’d like to hit on the actual character.

Thanks!

‘.’ is indeed a wildcard (or a “metacharater”). It matches anything
except newline (maybe one or two others - see Pickaxe for details).

Escape it with a backslash to match a literal ‘.’.

Only the newline unless you’re in multiline mode (ref: Pickaxe pg 61)
