](https://github.com/dtolnay/faketty/actions?query=branch%3Amaster) A wrapper binary to exec a command in a pty, even if redirecting the output. This allows logging the stdout and stderr (separately) of a process, without the output being different from what you'd see in the terminal if you weren't logging anything. ```console $ cargo install faketty ``` ```console $ faketty bazel build :target >log/out 2>log/err ~~~~~~~~~~~~~~~~~~~ command to run ```
## Background When redirecting stdout/err to a pipe or file, a process may detect the output is no longer going to a tty (because it has no width/height, baud rate, etc) and may change its behavior accordingly. For example many programs that involve a progress bar or colored text in a terminal disable those things when the output is not going to a terminal. There is a [script(1)] command which makes it possible to redirect a command's terminal-style output by executing it inside a pseudoterminal (pty) – a bidirectional pipe that also has width, height, etc and tricks the process into thinking it is talking to a real terminal. However, `script` only uses a single pty, which makes it impossible to demultiplex stdout and stderr to different places. [script(1)]: https://man7.org/linux/man-pages/man1/script.1.html The `faketty` command in this repo is similar to `script --quiet --return --command '...' /dev/null` except that it preserves distinct stdout and stderr streams.
