我会这样做：
find /directory -mtime -10 -size +15k
的/directory是基本目录，其中搜索被预成形（通过递归默认）。
-mtime 10 意味着它将查找在过去 10 天内修改过的文件：
Run Code Online (Sandbox Code Playgroud)-mtime n File's data was last modified n*24 hours ago. See the comments for -atime to understand how rounding affects the interpretation of file modi- fication times.
-size 15k 意味着它将查找大于 15 KB 的文件：
Run Code Online (Sandbox Code Playgroud)-size n[cwbkMG] File uses n units of space, rounding up. The following suffixes can be used: `b' for 512-byte blocks (this is the default if no suffix is used) `c' for bytes `w' for two-byte words `k' for Kilobytes (units of 1024 bytes) `M' for Megabytes (units of 1048576 bytes) `G' for Gigabytes (units of 1073741824 bytes) The size does not count indirect blocks, but it does count blocks in sparse files that are not actually allocated. Bear in mind that the `%k' and `%b' format specifiers of -printf handle sparse files differently. The `b' suffix always denotes 512-byte blocks and never 1 Kilobyte blocks, which is different to the behaviour of -ls. The + and - prefixes signify greater than and less than, as usual, but bear in mind that the size is rounded up to the next unit (so a 1-byte file is not matched by -size -1M).
