Don't understand quite would you mean---and I'm not quite sure why it would
help. The sudo/fakeroot completion code already exists and is reliable.
It can be enabled by uncommenting the following lines:
# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc).
if [ -f /etc/bash_completion ]; then
~/.bashrc or /etc/bash.bashrc
The code itself is implemented in:
Specifically the functions:
# A meta-command completion function for commands like sudo(8), which need to
# first complete on a command, then complete according to that command's own
# completion definition - currently not quite foolproof (e.g. mount and umount
# don't work properly), but still quite useful
To deal with this, the completion is called with the new PATH contain */sbin:
PATH=$PATH:/sbin:/usr/sbin:/usr/local/sbin _command $1
complete -F _root_command $filenames sudo fakeroot
which setups up the the `sudo' and `fakeroot' commands lines to be
re-evaluated after having their first item removed (eg. "sudo "). The
completion from the point done on the new, expanded path (including /sbin).
I believe it would be useful to have this enabled on a system-wide basis
and as the default. It should help encourage people to use sudo aswell.
