to the fact that the /bin/sh set command always sets the exit status to 0, so testing $? will not help discover if getopt found an error if getopt is used via "set -- `getopt ....`". (POSIX 1003.2 D11 draft says that the sh set command must return 0 as the exit status.) I think that POSIX is wrong or that is is not well enough specified to allow the result of the set to be the exit status of the getopt. But considering the sequential nature of execution, the set is done last and is the "last command" and therefore must be the one to set the exit status. At least there is a work-around for shell scripts. |
