# These flags should be available everywhere according to man knife
knife_general_flags=( --help --server-url --key --config --editor --format --log_level --logfile --no-editor --user --print-after --version --yes )
# knife has a very special syntax, some example calls are:
# knife status
# knife cookbook list
# knife role show ROLENAME
# knife data bag show DATABAGNAME
# knife role show ROLENAME --attribute ATTRIBUTENAME
# knife cookbook show COOKBOOKNAME COOKBOOKVERSION recipes
# The -Q switch in compadd allow for completions of things like "data bag" without having to go through two rounds of completion and avoids zsh inserting a \ for escaping spaces
