這是什麼意思 pkgname_glob - BBS

pkgname_glob Specify one of these: a full pkgname, a pkgname
without version, a shell glob pattern in which you
can use wildcards `*', `?', and `[..]', an
extended regular expression preceded by a colon
`:', or a date range specification preceded by
either `<' or `>'. See pkg_glob(1) for details
and concrete examples.

我想知道這一段的意思
不知道有沒有前輩可以跟我說一下
小弟有些專有名詞都不認識....
