I try to parse a expression like this with my regex:

FIRST SECOND ARG1=$value ARG2="with space"

There can be any number of arguments.

example: HELLO VERSION MIN=$min MAX=$max USER="xxx" PASSWORD="yyy"

result: HELLO - VERSION - PASSWORD - "yyy"

desired result: HELLO - VERSION - MIN - $min - MAX - $max - USER - "xxx" - PASSWORD - "yyy"

My regex is ([\w\d] ) ([\w\d] )(?: ([\w\d] )=("[^"]*"|[^" ]*))*

However, I do not get all the arguments, but only the last back. How can I fix it? It is too much for a regex?

You can match what's between quotes first, then the rest.

(["].*?["])|([[:alnum:]_\$] )
