Title:

  $ echo "don't fail me now rust" | tee -a log1 -a log2
  don't fail me now rust
  ubuntu at ubuntu:~$ ls -al log1 log2

  -rw-rw-r-- 1 ubuntu ubuntu 23 Dec 10 22:38 log2
  ubuntu at ubuntu:~$ cat log*
  don't fail me now rust
  don't fail me now rust

  
  4)
  $ echo "don't fail me now rust" | tee -a log1 -a log2
  error: the argument '--append' cannot be used multiple times

  For more information, try '--help'.

  
  If I replace "tee" with "gnutee" it works fine.
