Ubuntu: How to create script with auto-complete?


The Question: When I use program like svn and I type in Gnome Terminal:
svn upd
and hit Tab it's autocompleted to:
svn update
Is it possible to do something like that in my custom bash script?

You can use the http://www.gnu.org/s/bash/manual/bash...
Completion. Have look at /etc/bash_completion and /etc/bash_completion.d/* for
some examples.

All of the bash completions are stored in /etc/bash_completion.d/. So if you're
building software with bash_completion it would be worthwhile to have the deb/
make install drop a file with the name of the software in that directory.
Here's an example bash completion script for Rsync:
bash completion for rsync

have rsync &&
_rsync()
{
TODO: _split_longopt

local cur prev shell i userhost path

COMPREPLY=()
cur=`_get_cword`
prev=${COMP_WORDS[COMP_CWORD-1]}

_expand || return 0

case "$prev" in
--@(config|password-file|include-from|exclude-from))
_filedir
return 0
;;
-@(T|-temp-dir|-compare-dest))
_filedir -d
return 0
;;
-@(e|-rsh))
COMPREPLY=( $( compgen -W 'rsh ssh' -- "$cur" ) )
return 0
;;
esac

case "$cur" in
-*)

find which remote shell is used

if [[ "$shell" == ssh ]]; then
remove backslash escape from :

escape spaces; remove executables, aliases, pipes
and sockets; add space at end of file names

It would likely be worthwhile to review one of the bash completion files in
there that most closely matches your program. One of the simplest examples is
the rrdtool file.

I'm six months late but I was looking for the same thing and found this:
You'll have to create a new file:
/etc/bash_completion.d/foo
For a static autocompletion (--help / --verbose for instance) add this:
_foo()
{
local cur prev opts
COMPREPLY=()
cur="${COMP_WORDS[COMP_CWORD]}"
prev="${COMP_WORDS[COMP_CWORD-1]}"
opts="--help --verbose --version"
