# Description I'm not sure if "is-terminal" is the best name for this command as there is also "term size". Uses [`is_terminal()`](https://doc.rust-lang.org/stable/std/io/trait.IsTerminal.html#tymethod.is_terminal) which is cross-platform. Possible alternative names: * `term is-tty --stdout` * `term is-tty stdout` * `term is-terminal stdout` If multiple streams are provided an error is returned. The error span covers all arguments as the incompatible one is not known. This may be new? Fixes #10517 # User-Facing Changes * Add `is-terminal` to check if stdin, stdout, or stderr are a terminal (TTY) # Tests + Formatting The nu tests always redirect stdin, stdout, and stderr so a positive test case is not possible without extra work - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` # After Submitting The new command will be added automatically --------- Co-authored-by: Darren Schroeder <343840+fdncred@users.noreply.github.com>
