When looking for a nodepath you can use special regex (described here).
There is the * which stands for none or more characters and
there is the ? which stands for exactly one char.
But is there an option for looking for “none or one” character?
[ ,?] doesn’t work, btw.
EDIT: what does  (empty brackets) actually match? i noticed it doesn’t match “” (no chars).

according to that i think  means char range, just like regex
Thanks for the reply
I know that  is for ranges and arrays of chars, but what does it match without any content? just “”. Is that invalid syntax?
And still I’d like to know if there is a special sign for “none or exactly one character”
Wait, these are not regular expressions at all! Just simple globbing patterns.
man 7 glob
thanks! that helps me a lot
