linux基础_find命令

常用命令

清理15天前的文件

find /path/to/directory -type f -mtime +15 -exec rm {} \;

find获取文件名匹配a.log或b.log的文件

find /path/to/directory -type f \( -name "a.log" -o -name "b.log" \)

注：括号 ( 和 ) 是用来对表达式进行分组的，以确保逻辑的正确性。因为在命令行中，括号通常被用作特殊字符（用于命令组合、子shell等），为了在 find 命令中正确解释括号作为表达式的一部分，需要使用反斜杠进行转义。这样可以确保括号被正确传递给 find 命令进行处理。

查找并清理时间点前生成的文件

find . -type f -not -newermt "2024-03-07 09:35:00" -name "aaa.log*"  -exec rm {} \;

查找并清理时间点后生成的文件

find . -type f -newermt "2024-03-07 09:35:00" -name "aaa.log*"  -exec rm {} \;

      ( EXPR )   ! EXPR   -not EXPR   EXPR1 -a EXPR2   EXPR1 -and EXPR2
      EXPR1 -o EXPR2   EXPR1 -or EXPR2   EXPR1 , EXPR2

normal options (always true, specified before other expressions):
      -depth --help -maxdepth LEVELS -mindepth LEVELS -mount -noleaf
      --version -xautofs -xdev -ignore_readdir_race -noignore_readdir_race
