-maxdepth option after a non-option AND find: paths must precede expression
提问by MFIHRI
Hope someone can help with this:
希望有人可以帮助解决这个问题：
Am trying to delete session files on /tmp with this command:
我正在尝试使用以下命令删除 /tmp 上的会话文件：
find /tmp -name 'sess_*' -user Username -maxdepth 1 $CMD {} \;
but I got these errors:
但我收到了这些错误：
find: warning: you have specified the -maxdepth option after a non-option argument -name, but options are not positional (-maxdepth affects tests specified before it as well as those specified after it). Please specify options before other arguments.
find: paths must precede expression Usage: find [-H] [-L] [-P] [path...] [expression]
find: 警告：您在非选项参数 -name 之后指定了 -maxdepth 选项，但选项不是位置性的（-maxdepth 影响在它之前指定的测试以及在它之后指定的测试）。请在其他参数之前指定选项。
find: paths must precede expression Usage: find [-H] [-L] [-P] [path...] [expression]
I looked for solutions over the web but could not find any. I have deleted other tmp files with other commands and wonder if that affected some volume or socket.
我在网上寻找解决方案，但找不到任何解决方案。我已经用其他命令删除了其他 tmp 文件，想知道这是否影响了某些音量或套接字。
Thank you in advance
先感谢您

findhas three types of options: options that are used to match files (e.g. -name, -user), options that specify actions to perform on the matched files (-print, -exec), and options that control the overall behavior of the command (e.g. -maxdepth, -xdev). The third type must be put before the other two. So it should be:
find具有三种类型的选项：用于匹配文件的选项（例如-name, -user）、指定对匹配文件执行的操作的选项（-print, -exec）以及控制命令整体行为的选项（例如-maxdepth, -xdev）。第三种必须放在其他两种之前。所以应该是：
find /tmp -maxdepth 1 -name 'sess_*' -user Username -exec $CMD {} \;
