How does the POSIX shell grammar http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_10
accept a simple command with assignment such as:
The first word here must be accepted as token
ASSIGNMENT_WORD by Rule 7b (although this rule is not specified explicitly to apply to the productions involving
ASSIGNMENT_WORD , but I guess that is understood).
Then there is no way to accept the second word. The only way to try to reduce it would be with
cmd_word production, but that requires Rule 7b to say this is a
WORD and Rule 7b does not say anything about words that do not contain
One has to add to Rule 7b a statement such as:
If the TOKEN does not contain `=` then it is a `WORD`.
Without this, the grammar as written currently is faulty. Am I correct?
