Rc.d bash_completion

Question

Hi,
I've now finished my bash_completion script for the command rc.d which was introduced some time ago.
If you have some advices just post them here.

_rc_d()
local cur prev initdir long_opts cmds shoptExtglob
shoptExtglob="$(shopt -p | grep extglob)"
shopt -s extglob
long_opts='list help'
initdir=/etc/rc.d
cmds="$(sed '/#.*sh/,/^.*case\s*"*\${*1}*"*.*/ { /^.*case\s*"*\${*1}*"*.*/!d };s/^.*case\s*"*\${*1}*"*.*/;;/g;/;;/,/^\s*.*)\s*$/ !d;/^\s*.*)\s*$/ !d;/\*/d;/;;/d;s/\s*//g;s/)//g;s/|/ /g' ${initdir}/!(*functions*) | LANG=C sort -u | tr '\n' ' ')"
_get_comp_words_by_ref cur prev
cmd="${COMP_WORDS[1]}"
if [[ "${cmd}" =~ ^(${cmds// /|}|${long_opts// /|})$ ]] && [ -n "${cmd}" ]; then
COMPREPLY+=( $( compgen -W '`grep -El "^[ ]*[^ ]*${cmd}[|\)][^ ]*\)*[ ]*$" ${initdir}/* | sed 's#${initdir}/##'`' -- "$cur" ) )
else
COMPREPLY=( $( compgen -W '${long_opts} ${cmds}' -- "$cur" ) )
fi
${shoptExtglob}
return 0
complete -F _rc_d rc.d
# Local variables:
# mode: shell-script
# sh-basic-offset: 4
# sh-indent-comment: t
# indent-tabs-mode: nil
# End:
# vim: ts=2 sw=2 et filetype=sh
Maybe it could be added to initscripts-package.
Kind regards,
Andrwe
