   3 ## Testing/debugging
   4
   5 ### stderr redirection
   6
   7 If something needs to be printed for debugging (e.g. using `eprintln!()` or
   8 `dbg!()`), output redirection can be used. Open a second terminal and get the
   9 file name of the terminal using the `tty` command:
  10 ```sh
  11 $ tty
  12 /dev/pts/6
  13 ```
  14
  15 Now, simply run the installer using:
  16 ```sh
  17 $ cargo run 2>/dev/pts/6
  18 ```
  19
  20 All stderr output will then show up in the other terminal.
  21
  22 ### Specific terminal size
  23
  24 To test the installer with a specific output size, the `stty` command can be
  25 used. For example, to set it to a standard 80x25 terminal:
  26 ```sh
  27 $ stty columns 80 rows 25
  28 ```
