Subject: [PATCH 1/2] Introduce new completion for Linux task capabilities
Date: Fri, 26 Feb 2021 10:55:57 +0300 [thread overview]
Message-ID: <20210226075558.883716-1-ar@cs.msu.ru> (raw)
This is intended for use on Linux-based systems only.
The next patch introduces a completion for setpriv(1), which actively
uses _capability_names. As for _capabilities, there are currently no
users of this function, but I believe some utilities that handle caps
may actually want to use it (neither setpriv(1) nor setcap/getcap(8),
for instance, want to offer the cap names themselves as completion
results; instead they want to prefix each name or a comma-separated
sequence of names), and if not yet — it is still available to be
manually compdeffed.
