Add Custom Tab Auto-Completion to your Bash Scripts

I like shoving little methods in my bash ~/.profile ... to complete the laziness I added tab auto-completion.

Create a method that generates the tab options then use "complete" to assign it to your custom method:

# a method which returns all my project dirs via COMPREPLY - note the use of 
# compgen and ls /clients within backticks, that's where you want to do
# your own thang
function _clientdirs()
 {
        local curw
        COMPREPLY=()
        curw=${COMP_WORDS[COMP_CWORD]}
        COMPREPLY=($(compgen -W '`ls /clients`' -- $curw))
        return 0
}

# my 'q' shortcut method to run a queue script in one of my projects
 function q()
{
        if [ $# -eq 1 ]
        then
                php /clients/$1/core/tools/run_queue.php local
        else
                php core/tools/run_queue.php local
        fi
}

 # assigning the complete method to my method
complete -F _clientdirs -o dirnames q
