apt-get update -qqy

第一次看到-qq参数,觉得比较新奇,特意确认了下:

-q, --quiet

Quiet. Produces output suitable for logging, omitting progress indicators. More q's will produce more quiet up to a maximum of two. You can also use -q=# to set the quiet level, overriding the configuration file. Note that quiet level 2 implies -y, you should never use -qq without a no-action modifier such as -d, --print-uris or -s as APT may decided to do something you did not expect.

所以按照说明,-qq一般是搭配y选项的。
这个参数经常在docker的静默安装指令中使用。
