Public bug reported:
Binary package hint: bash-completion
When passwordless authentication is setup, scp allows autocompletion of
the nature:
scp host:/home/martin/Doc <TAB>
This appears to be broken in Karmic (Kubuntu anyway) as this line in
/etc/bash_completion.d/ssh causes local expansion of directories:
_expand || return 0
This means that, typing the above expands to /home/martin/Documents on
the LOCAL machine, not on the remote.
My revised version, that now works, looks like this for the _scp
function:
_scp()
{
local cur userhost path
COMPREPLY=()
cur="${COMP_WORDS[COMP_CWORD]}"
prev="${COMP_WORDS[COMP_CWORD-1]}"
# replaced by the above 2 lines
#cur=`_get_cword ":"`
## Removed to avoid local expansion
#_expand || return 0
if [[ "$prev" == *:* ]]; then
# This happens when there is a : in the path
local IFS=$'\t\n'
# remove backslash escape from :
cur=${cur/\\:/:}
userhost=${COMP_WORDS[COMP_CWORD-2]}
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/[^\/]$/& /g' ) )
return 0
fi
[[ "$cur" == */* ]] || _known_hosts -c -a
local IFS=$'\t\n'
COMPREPLY=( "${comprep...@]}" $( command ls -aF1d $cur* \
2>/dev/null | sed \
-e "s/[][(){}<>\",:;^&!$&=?\`|\\ ']/\\\\&/g" \
-e 's/[*@|=]$//g' -e 's/[^\/]$/& /g' ) )
return 0
}
complete -F _scp $nospace scp
