Bash has a command that will show whether a command is an alias, a function or an executable in your path (and, if so, where):
Bash 有一个命令，可以显示命令是路径中的别名、函数还是可执行文件（如果是，则显示在何处）：
type -a youtube-dl
It's much better than which.
它比which.

If you can't find it with which(or whereis) then it could be:
如果您无法使用which(或whereis)找到它，那么它可能是：
- a function defined in .bashrc or .profile (or some other file the shell loads on startup or login)
- an alias defined in one of the above files.
- 在 .bashrc 或 .profile 中定义的函数（或 shell 在启动或登录时加载的其他一些文件）
- 在上述文件之一中定义的别名。
You can search your environment for youtube-dl:
您可以在您的环境中搜索 youtube-dl：
$ set | grep youtube-dl
or save it to some file and load it into a texteditor:
或将其保存到某个文件并将其加载到文本编辑器中：
$ set >myenv
$ open -a textedit myenv
and for the aliases:
和别名：
$ alias >myalias
or
或者
$ alias | grep youtube-dl

Have you tried
你有没有尝试过
whereis youtube-dl

Otherwise you could just search for it:
否则你可以只搜索它：
find / -name youtube-dl
