Hmm. I suppose by extension that `id -Gn` should accept -1 too. But do you really want to support group names with spaces? `groupadd` for example won't allow this. I suppose integration with LDAP etc. might get arbitrary group names. Note POSIX is quite specific about the output format for `id`: "−G Output all different group IDs (effective, real, and supplementary) only, using the format "%u\n". If there is more than one distinct group affiliation, output each such affiliation, using the format " %u", before the <newline> is output." That suggests to me that \n is used to distinguish the three types of IDs. So -1 would have to override that functionality. cheers, Pádraig.
