How to enable regex support in zsh?

Answer 1

ls [0-9].jpg
The syntax of zsc is not always the same as bash.

Answer 2

The expression ls +([0-9]).jpg doesn't work in zsh, but it does in bash.

It does not work in bash, at least in default settings:

$ ls +([0-9]).jpg
bash: syntax error near unexpected token `('

Bash does not support regular expressions, it has extended globbing:

If the extglob shell option is enabled using the shopt builtin, several extended pattern matching operators are recognized.

Answer 3

These are not regular expressions, these are file masks - bash supports *, ?, ~ and a simple list with ranges in square brackets []
But this is NOT a regular expression, it does not fall under any regexp standard. There are no such quantifiers.
