MySQL Bugs: #12361: command line client:misleading error message for -raw option (--raw)

Bug #12361	command line client:misleading error message for -raw option (--raw)
Submitted:	3 Aug 2005 21:49	Modified:	4 Aug 2005 6:57
Reporter:	Roland Bouman	Email Updates:
Status:	Not a Bug	Impact on me:	None
Category:	MySQL Server	Severity:	S4 (Feature request)
Version:	5.0.10 (occurs in command line client)	OS:	Windows (Win XP Professional SP2)
Assigned to:		CPU Architecture:	Any

Description:
Invoking the command line tool with -raw (instead of --raw) returns a misleading error message:

mysql: unknown option '-a'

It was expected that the tool would return an error message referring to '-raw', not '-a'

How to repeat:
C:\Program Files\MySQL\MySQL Server 5.0\bin>mysql -raw
mysql: unknown option '-a'

Suggested fix:
Return an error message saying that -raw is an unknown option

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.mysql.com/documentation/ and the instructions on
how to report a bug at http://bugs.mysql.com/how-to-report.php

Additional info:

Standard GNU getopts() functions are used to process options. (See getopts(3) manual page on any UNIX for details). This is how they works: when -abc (with one '-') word is found in the command line, it is interpreted as -a -b -c. In your case it will be -r -a -w, but mysql does not support -a option (http://dev.mysql.com/doc/mysql/en/mysql.html). That is why this error message is displayed.

Ok, sorry to have bothered you. I was not aware that this behaviour is in fact documented.
