Does ksh93 support +o type options with its getopts(1) builtin?

ksh93 supports long options the same way as introduced by Sun Microsystems in Spring 2004 for getopt(3), Bourne Shell and ksh88.



You may e.g. use:



getopt(argc, argv, "V(version)");


to establish a long --version alias to the short option -V.



However ksh93 does not use the getopt(3) from Solaris libc but an own implementation that internally is used to support short options that start with a + sign.



Is there a way to use this feature with the ksh93 builtin getopts(1)implementation and iff, how does it work?

    Try getopts --man 2>&1 | more in ksh93 for details.

  • I discovered this some time ago already, I however have been unable to understand it since there are no examples and the ksh concept seems to complex as it includes support for --help IIRC. Do you know examples for this +o feature?

  • Yes, by brain is not tuned to parse that man page either. There are plenty of examples in the ast-open source code though.

Accessing regular linux commands in Huawei's Dopra Linux

4 Backstory: I have a Huawei HG8245 router in my house and I want to change the default username/password. I've tried following this guide but the config file always gets reset. My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials. The first shell I gain access to looks like this: WAP> Pressing "?" gives me a list of available commands which I've pasted here, the two interesting ones are "su" and "shell".
