Bash tab completion for Fabric in Ubuntu

If you going to be using Fabric much (which you will, if you know what’s good for you) then having tab auto-completion of your tasks is a must. There’s already a ticket out for this (targeting version 1.1) but, in the meantime, I’ve adapted Adam Vanderburg’s OS X completion script for Debian/Ubuntu.

To install, either copy the script into /etc/bash_completion.d/ (if you want it system-wide) or append it to ~/.bash_completion (if you want it for your account only).

have fab && {
_fab_completion()
{
    COMPREPLY=() 
    local cur tasks
    tasks=$(fab --shortlist 2>/dev/null)
    _get_comp_words_by_ref cur
    COMPREPLY=( $(compgen -W "${tasks}" -- ${cur}) )
}
complete -F _fab_completion fab
}

P.S I only modified the original because my version of which doesn’t support the -s switch. You could probably get away just with replacing -s with > /dev/null, but once I start modifying something I can never resist the urge to fiddle.
