Environment:

Linux

Sprint: 5.5.50

 Description   

Description:
There are weird exit codes of some utilities:

`mysql_waitpid --help` returns 255 instead of 0

`mysqladmin --help` returns 1 instead of 0

both of them accept 

'--help'

(or '-?') as valid option according to the documentation

How to repeat:

$> mysql_waitpid --help &>/dev/null
 
$> echo $?
 
 
 
$> mysqladmin --help &>/dev/null
 
$> echo $?

Current resutls:

255
 
1

Expected results:

0
 
0

Thanks for the report.

Reasoning from MDEV-4905 does not apply here, because the non-zero code is returned even when mysqladmin --help is run with a perfectly valid set of parameters.
