1. I want to execute the find / -name user.ibd command in my docker mysql container to find some files. But the terminal prompts me： bash: find: command does not exist.

2. Then I execute which find to confirm whether this command exists， but it prompts: bash: which: command does not exist.

3. I execute echo $PATH and try to find the find and which in various paths, but it seems that there are no such commands. My operations are below:

Any idea would be appreciated.
