Thanks to shellholic's answer, I was able to make it (somewhat) work for sftp. First, create the file /etc/bash_completion.d/sftp with the following content:
# custom sftp(1) based on scp# see http://askubuntu.com/questions/14645/is-it-possible-to-get-tab-completion-with-sftp#_sftp(){ local configfile cur userhost path prefix COMPREPLY=() cur=`_get_cword ":"` _expand || return 0 if [[ "$cur" == *:* ]]; then local IFS=$'\t\n' # remove backslash escape from : cur=${cur/\\:/:} userhost=${cur%%?(\\):*} path=${cur#*:} # unescape spaces path=${path//\\\\\\\\ / } if [ -z "$path" ]; then # default to home dir of specified user on remote host path=$(ssh -o 'Batchmode yes' $userhost pwd 2>/dev/null) fi # escape spaces; remove executables, aliases, pipes and sockets; # add space at end of file names COMPREPLY=( $( ssh -o 'Batchmode yes' $userhost \ command ls -aF1d "$path*" 2>/dev/null | \ sed -e "s/[][(){}<>\",:;^&\!$=?\`|\\ ']/\\\\\\\\\\\\&/g" \ -e 's/[*@|=]$//g' -e 's/[^\/]$/& /g' ) ) return 0 fi if [[ "$cur" = -F* ]]; then cur=${cur#-F} prefix=-F else # Search COMP_WORDS for '-F configfile' or '-Fconfigfile' argument set -- "${COMP_WORDS[@]}" while [ $# -gt 0 ]; do if [ "${1:0:2}" = -F ]; then if [ ${#1} -gt 2 ]; then configfile="$(dequote "${1:2}")" else shift [ "$1" ] && configfile="$(dequote "$1")" fi break fi shift done [[ "$cur" == */* ]] || _known_hosts_real -c -a -F "$configfile""$cur" fi # This approach is used instead of _filedir to get a space appended # after local file/dir completions, and $nospace retained for others. local IFS=$'\t\n' COMPREPLY=( "${COMPREPLY[@]}" $( command ls -aF1d $cur* 2>/dev/null | sed \ -e "s/[][(){}<>\",:;^&\!$=?\`|\\ ']/\\\\&/g" \ -e 's/[*@|=]$//g' -e 's/[^\/]$/& /g' -e "s/^/$prefix/") ) return 0}complete -o nospace -F _sftp sftpThen in bash you need to execute . /etc/bash_completion.d/sftp in order to load the script.
All I really did was copy/paste the scp completion script from /etc/bash_completion.d/ssh and replace scp occurences with sftp.
