“Illegal option” error when using find on macOS

问题:

I am trying to list the files only with the letter "R" at the end. I used find as follows in macOS Terminal,

find -type f -name '*R' 

But I got the message saying illegal option --t.

回答1:

The first argument to find is the path where it should start looking. The path . means the current directory.

find . -type f -name '*R'

You must provide at least one path, but you can actually provide as many as you want:

find ~/Documents ~/Library -type f -name '*R'
