[Bash-completion-devel] Bash completion for lpr, and lprm

[Marcin Szamotulski]

Hello,

I wrote a bash completion script for lpr (lp) and lprm commands.

Best regards,

# lpr(1) and lprm(1) completions by Marcin Szamotulski <mszamot at gmail.com> March 2011

# This script uses two functions from 'base': _known_hosts_real and _user_at_host.
# to complete -H and -U switches of the lpr command (-h and -U of lprm).
