Make scp autocomplete server names and file/folders names on Ubuntu 16.04

I was struggling to make scp auto-complete servers names but also complete local files names under Ubuntu bash.

For some strange reason, out of the box solutions just didn't work, I could make the server completion work or the local files completion work but not both.
And I'm not even talking about remote file names over SSH, just local file names.

Installing auto-complete on Ubuntu if not already there:

Replace /etc/bash_completion.d/ssh with the following content:

         ssh()

         {

         local cur prev opts

         COMPREPLY=()

         cur="${COMP_WORDS[COMP_CWORD]}"

         prev="${COMP_WORDS[COMP_CWORD-1]}"

         opts=$(grep '^Host' ~/.ssh/config | grep -v '[?*]' | cut -d ' ' -f 2-)

        

         _longopt

         RESULT="$COMPREPLY $opts"

         COMPREPLY=( $(compgen -W "$RESULT" -- ${cur}) )

        

         if [[ "$cur" == -* ]]; then

         COMPREPLY=( $( compgen -W "$( $1 --help 2>&1 | \

         sed -ne 's/.*\(--[-A-Za-z0-9]\{1,\}=\{0,1\}\).*/\1/p' | sort -u)" \

         -- "$cur" ) )

         [[ $COMPREPLY == *= ]] && compopt -o nospace

         elif [[ "$1" == @(mk|rm)dir ]]; then

         _filedir -d

         else

         _filedir

         fi

        

         return 0

         }

         complete -F _ssh ssh

         complete -F _ssh scp

Enjoy !
