Package: cryptsetup
Version: 2:1.0.4+svn26-1
Severity: wishlist
Tags: patch
I have created a Bash programmable completion script for cryptsetup
which will complete based on option name, action, and device/mapping
name. The file can be shipped in /etc/bash_completion.d/ and it will be
sourced by /etc/bash_completion if users have Bash completion turned on.
I have found the script to be quite useful for quickly completing
commands and I hope you find it useful as well.
Cheers,
Kevin
