mc find 命令用来查询对象。语法如下：
C:\> mc find -h
NAME:
mc find - search for objects
USAGE:
mc find PATH [FLAGS]
FLAGS:
--exec value spawn an external process for each matching object (see FORMAT)
--ignore value exclude objects matching the wildcard pattern
--name value find object names matching wildcard pattern
--newer-than value match all objects newer than L days, M hours and N minutes
--older-than value match all objects older than L days, M hours and N minutes
--path value match directory names matching wildcard pattern
--print value print in custom format to STDOUT (see FORMAT)
--regex value match directory and object name with PCRE regex pattern
--larger value match all objects larger than specified size in units (see UNITS)
--smaller value match all objects smaller than specified size in units (see UNITS)
--maxdepth value limit directory navigation to specified depth (default: 0)
--watch monitor a specified path for newly created object(s)
--config-dir value, -C value path to configuration folder (default: "C:\\Users\\Administrator\\mc")
--quiet, -q disable progress bar display
--no-color disable color theme
--json enable JSON lines formatted output
--debug enable debug output
--insecure disable SSL certificate verification
--help, -h show help
UNITS
--smaller, --larger flags accept human-readable case-insensitive number
suffixes such as "k", "m", "g" and "t" referring to the metric units KB,
MB, GB and TB respectively. Adding an "i" to these prefixes, uses the IEC
units, so that "gi" refers to "gibibyte" or "GiB". A "b" at the end is
also accepted. Without suffixes the unit is bytes.
--older-than, --newer-than flags accept the string for days, hours and minutes
i.e. 1d2h30m states 1 day, 2 hours and 30 minutes.
FORMAT
Support string substitutions with special interpretations for following keywords.
Keywords supported if target is filesystem or object storage:
{} --> Substitutes to full path.
{base} --> Substitutes to basename of path.
{dir} --> Substitutes to dirname of the path.
{size} --> Substitutes to object size of the path.
{time} --> Substitutes to object modified time of the path.
Keywords supported if target is object storage:
{url} --> Substitutes to a shareable URL of the path.（1）在“local”帐户下的所有存储桶中查找所有“ping.txt”。
D:\server\minio>mc find local --name "ping.txt" local/files/ping.txt
（2）在“local/files”下查找所有带有“.txt”扩展名的对象。
D:\server\minio>mc find local/files --name "*.txt" local/files/ping.txt
（3）仅在“local/files”下查找没有目录组件的对象名称。
D:\server\minio>mc find local/files --name "*" -print {base}
ping.txt
start-minio.bat（4）在“s3/photos”下查找所有带有“.jpg”扩展名、前缀为“album”的图像。
C:\> mc find s3/photos --name "*.jpg" --path "*/album*/*"
（5）使用“s3/photos”下的正则表达式查找所有带有“.jpg”、“.png”和“.gif”扩展名的图像。
C:\> mc find s3/photos --regex "(?i)\.(jpg|png|gif)$"
（6）在“s3/bucket”下找到所有带有“.jpg”扩展名的图像并复制到“play/bucket”*连续*。
C:\> mc find s3/bucket --name "*.jpg" --watch --exec "mc cp {} play/bucket"（7）查找并生成有效期为 7 天的公共 URL，适用于“s3”帐户下大小介于 64 MB 和 1 GB 之间的所有对象。
C:\> mc find s3 --larger 64MB --smaller 1GB --print {url}（8）在“local/images”下找到上周创建的所有对象。
D:\server\minio>mc find local/images --newer-than 7d local/images/0f78ad1e685e9e972e3780ebfbdf2192.jpeg
（9）查找所有创建时间超过 2 天 5 小时 10 分钟的对象，并排除“local”下带有“.jpg”扩展名的对象。
D:\server\minio>mc find local --older-than 2d5h10m --ignore "*.jpg" local/images local/images/0f78ad1e685e9e972e3780ebfbdf2192.jpeg
（10）列出“local”下最多 3 级子目录的所有对象。
D:\server\minio>mc find local --maxdepth 3 local/files local/files/ping.txt local/files/start-minio.bat local/images local/images/0f78ad1e685e9e972e3780ebfbdf2192.jpeg local/images/20210703221135.jpg
