[Bash-completion-devel] Completion based on existing options

[Gioele Barabucci]

Hi,

I am creating a bash completion for pw [1]. pw deals with password 
databases: text files in which each line (entry) has its own long ID. I 
would like to use bash completion to automatically complete these IDs.

My current code [2] can extract the IDs from the default database 
`passwords`. The basic `pw-show 1e3<TAB>` works fine. Now I would like 
to make the completion work even when other databases are requested 
using the `-d` (or `--db`) option, for example `pw-show -d team a03<TAB>`.

What is the best way to look into the already-given arguments to find 
whether the `-d` option has been given and what is its value?

Regards,
