BashCompletion

From RdiffBackupWiki

# # # # # # # # # # # # # # # # # # # # # # 
# A basic bash-completion for rdiff-backup
#
# Developed for 1.1.15 but can be "ported" to older version
# by modifying the lists of available options.
#
# This script supplies a completion of --long-options.
# It also tries to judge when to complete and not to complete.
#
# I will most likely upgrade this scripts with more advanced
# features such as the ability to recognize increments, etc.
#
# Feel free to send comments or suggestions to andreas@arrakis.se
