Nobody's going to write: foo=bar for arg And expect that "for" to be looked up in $PATH. On the other hand, a shell implementation may want to allow: 2> /dev/null [[ $a -eq $b ]] Or TIMEFMT=3 time cmd ...

In cmd arg cmd is the WORD token identified as "cmd_name" In var=value < file cmd arg cmd is identified as "cmd_word". In those two examples, "cmd" is the "name of the command" being executed, but neither cmd_word nor cmd_name have to be the command's name like in $(echo cmd arg1) arg2 where the cmd_name is $(echo cmd arg1) but the command's name is "cmd" (assuming the default value of $IFS) or dryrun=; $dryrun cmd arg where cmd_name is $dryrun but the command name is "cmd". The distinction between cmd_name and cmd_word here is about the token having different constraints when it's preceded by redirections/assignments and not (namely whether keywords are allowed). Maybe "cmd_word_no_keyword" would be a better wording for "cmd_name".

[1003.1(2013)/Issue7+TC1 0001276]: incorrect resolution in bugid:839
The following issue has been SUBMITTED. == http://austingroupbugs.net/view.php?id=1276 == Reported By:stephane Assigned To: == Project:1003.1(2013)/Issue7+TC1 Issue ID: 1276 Category: Shell and Utilities Type: Error Severity: Objection Priority: normal Status: New Name: Stephane Chazelas Organization: User Reference: Section:2.10.2 shell grammar rules Page Number: Line Number: Interp Status: --- Final Accepted Text: == Date Submitted: 2019-07-30 13:11 UTC Last Modified: 2019-07-30 13:11 UTC == Summary:incorrect resolution in http://austingroupbugs.net/view.php?id=839 Description: As already raised in http://austingroupbugs.net/view.php?id=1094 and http://austingroupbugs.net/view.php?id=1100 (though the http://austingroupbugs.net/view.php?id=839 origin had not been identified then), now closed as rejected, the resolution of 839 broke rule 7. Now 7a becomes redundant, and 7b is no longer useful to qualify the difference between a a cmd_name and cmd_word. The difference as seen in earlier versions of the spec was to specify that keywords are not to be recognised as such when following redirections or assignments. With the 839 change, a "a=1 for bar" can no longer be parsed as a simple command as rule 7b now defers to rule 1 which means "for" does not give a "WORD" token any more. That defeats the point of having a cmd_word vs cmd_name distinction. If the point of 839 was to allow implementations to have keywords that contain = characters, then only 7a should have been modified to say: "if the token is a reserved word, return the token for that reserved word, otherwise apply 7b". Desired Action: Either undo the change for 839 (except for the "else" part) or go with the simpler/clearer grammar approach (at least when it comes to this particular issue) suggested in http://austingroupbugs.net/view.php?id=1100 or change the whole rule 7 to: 7. [Assignment preceding command name] a. [When the first word] If the TOKEN is exactly a reserved word, the token identifier for that reserved word shall result. Otherwise, 7b shall be applied. b. [Not the first word] If the TOKEN contains an unquoted (as determined while applying rule 4 from Token Recognition) character that is not part of an embedded parameter expansion, command substitution, or arithmetic expansion construct (as determined while applying rule 5 from Token Recognition): • If the TOKEN begins with '=', then the token WORD shall be returned. • If all the characters in the TOKEN preceding the first such form a valid name (see XBD Name), the token ASSIGNMENT_WORD shall be returned. • Otherwise, it is unspecified whether the WORD or ASSIGNMENT_WORD is returned. Otherwise, the token WORD shall be returned. Assignment to the name within a returned ASSIGNMENT_WORD token shall occur as specified in Simple Commands. == Issue History Date ModifiedUsername FieldChange == 2019-07-30 13:11 stephane New Issue 2019-07-30 13:11 stephane Name => Stephane Chazelas 2019-07-30 13:11 stephane Section => 2.10.2 shell grammar rules ==
