Well. In this package, the completions for ifdown and dhclient
are very different. E.g. in dhclient's completion, there's code that
looks like this:
if [[ "$cur" == -* ]]; then
COMPREPLY=( $( compgen -W '-p -d -q -1 -r -lf -pf -cf -sf -s -g -n -nw
-w' -- "$cur" ) )
else
_available_interfaces
The ifdown completion, on the other hand, has:
if [[ $cword -eq 1 ]]; then
_configured_interfaces
COMPREPLY=( $(compgen -W '${COMPREPLY[@]}' -- "$cur") )
I wonder what the difference between _available_interfaces and
_configured_interfaces is. Looks important.
