Why does Vim say "Vim: Warning: Input is not from a terminal"?

Question

vim

I run the command:
$ find -type f | xargs endsp | xargs vim
endssp simply prints the file name if it is text and contains trailing spaces.
Vim complains: "Vim: Warning: Input is not from a terminal". Works normally. But after exiting Vim, mintty does not respond to any keys. Sometimes Ctrl+D saves.

Answer 1

because vim is run as part of the pipe. if you need to edit files according to the list, you can do this: vim `find -type f | xargs endssp`

Answer 2

I like it better through pipes:
find -type f | xargs endsp | vim -

Answer 3

This command
will open a list of files with trailing spaces, not the files themselves.
