/usr/bin/sudo: invalid option -- '-'

[Michael Monreal]

Using haguichi-1.0.9-26.1.noarch on Fedora 15, when starting Haguichi I see the following on the console:

[mimox ~]$ haguichi
/usr/bin/sudo: invalid option -- '-'
usage: sudo -h | -K | -k | -L | -V
usage: sudo -v [-AknS] [-g groupname|#gid] [-p prompt] [-u user name|#uid]
usage: sudo -l[l] [-AknS] [-g groupname|#gid] [-p prompt] [-U user name] [-u
            user name|#uid] [-g groupname|#gid] [command]
usage: sudo [-AbEHknPS] [-r role] [-t type] [-C fd] [-g groupname|#gid] [-p
            prompt] [-u user name|#uid] [-g groupname|#gid] [VAR=value] [-i|-s]
            [<command>]
usage: sudo -e [-AknS] [-r role] [-t type] [-C fd] [-g groupname|#gid] [-p
            prompt] [-u user name|#uid] file ...

I guess whatever sudo is used for will not work in this case?

Hi Michael,

That's normal on systems with only plain sudo available. On startup Haguichi checks if the configured sudo command is still available by running "{configured sudo command} --help". Because sudo (unlike gksudo, gnomesu, kdesudo, etc) doesn't have the option --help, it's displaying the "invalid option" message.

Please be aware that without graphical sudo command on your system (i.e. Fedora), you need to set up the right permissions to start and stop the hamachi deamon in advance.

I've just committed a faster and cleaner way to check if a command exists on the system: http://bazaar.launchpad.net/~ztefn/haguichi/1.0/revision/202

Using this new method the reported message will not occur.
