I think you want the quiet flag.
我想你想要安静的旗帜。
zip -uq ${path}.zip ${path}
From the man pages:
从手册页：
-q --quiet Quiet mode; eliminate informational messages and comment prompts. (Useful, for example, in shell scripts and background tasks).

maybe you can try "add" instead of update(-u) ?
也许您可以尝试“添加”而不是 update(-u) ？
from man page:
从手册页：
add Update existing entries and add new files. If the archive does not exist create it. This is the default mode. update (-u) Update existing entries if newer on the file system and add new files. If the archive does not exist issue warning then create a new archive. freshen (-f) Update existing entries of an archive if newer on the file system. Does not add new files to the archive. delete (-d) Select entries in an existing archive and delete them.

Probably you should not tell zipto update an archive (-u). Without the -uswitch ziptries to add files to an archive, and should create non-existing archives without warnings.
可能您不应该告诉zip更新存档 ( -u)。没有-u开关zip尝试将文件添加到存档，并且应该创建不存在的存档而不会发出警告。

You can also remove unnecessary output lines and leave normal status info visible, but you first need to redirect the stderr to stdout. For example following command will extract from many zip files only some specific files, but will not show emnpty lines nor complain for not found files. In that way you still have some output for logging, debugging etc.
您还可以删除不必要的输出行并保留正常状态信息可见，但您首先需要将 stderr 重定向到 stdout。例如，以下命令将从许多 zip 文件中仅提取一些特定文件，但不会显示空行，也不会抱怨找不到文件。通过这种方式，您仍然有一些用于日志记录、调试等的输出。
unzip -jn archivedlogfiles\* \*logfile\* 2>&1 | grep -vE '^$|^caution.*'
Archive: archivedlogfiles1.zip
inflating: little_logfile_20160515.log
inflating: little_logfile_20160530.log
Archive: archivedlogfiles2.zip
Archive: archivedlogfiles3.zip
Archive: archivedlogfiles4.zip
Archive: archivedlogfiles5.zip
Archive: archivedlogfiles6.zip
Archive: archivedlogfiles7.zip
Archive: archivedlogfiles8.zip
inflating: little_logfile_20160615.log
inflating: little_logfile_20160630.log
Archive: archivedlogfiles9.zip
2 archives were successfully processed.
7 archives had fatal errors.
Basically your command would then look like this:
基本上你的命令看起来像这样：
zip -u ${path}.zip ${path} 2>&1 | grep vE '^zip\swarning.*'
