* wall: add --group optionJim Patterson2016-12-021-0/+4
| | | | | | | | | | | | | | | | The wall command on AIX supports a "-g" option to limit the message to a group of users by gid. Add compatibility to the Linux version. Thanks to Sami Kerola <kerolasa@iki.fi> for an initial skeleton implementation.

* bash-completion: use '\n' as IFS when ask for filenamesKarel Zak2013-09-301-0/+1
| | | | | | | | | | | | The bash completion for more(1) treats the space-separated pieces of filenames as different files. $ touch foo\ bar $ more foo<TAB> bar foo Reported-by: Ángel González <ingenit@zoho.com> Signed-off-by: Karel Zak <kzak@redhat.com>
* bash-completion: Don't offer short options where corresponding long one exists.Ville Skyttä2013-04-081-1/+1
| | | | | | | | | Users who know the short options can just hit the short option instead of tab, and it's not likely that it would be helpful to present a list of single character options to users who don't know them, doing so just unnecessarily trashes the list of suggestions.
