Overly Attached Argument

Flags can also take an argument. And there are multiple variants to this.

POSIX

Flags that require an argument consume the one next on the command line. But it can also be attached directly to the name with a = delimiter. And for shorthands, the delimiter can even be left out. Flags that take an optional argument do so only in the attached version.

Not all commands support each of these variants.

Non-POSIX

There are also some less recommended variants.

Like Flags consuming multiple arguments. Or using a different delimiter than =.
