英文:
Execute commands as if they're being executed directly in the terminal
问题
以下是已翻译的内容：
"这段代码定义了自定义终端命令（KeyboardShortcut）并执行它们：
use std::io::{stdout, Write};use std::process::Command;use termion::raw::IntoRawMode;struct KeyboardShortcut {key: char,description: &'static str,command: &'static str,}impl KeyboardShortcut {fn execute_command(&self, stdout: &mut impl Write) {Command::new("sh").arg("-c").arg(self.command).status();}}fn main() {let mut stdout = stdout().into_raw_mode().unwrap();// 在原始模式下执行一些操作let keyboard_shortcuts = vec![KeyboardShortcut {key: 'f',description: "Feat: adds a new feature to the application",command: "ls --color=always",}];stdout.flush().unwrap();// 在实际应用中，我使用了 `match`。keyboard_shortcuts[0].execute_command(&mut stdout);}
请注意，我不得不向命令添加 --color=always。这是因为如果命令不是直接在终端中执行（在这种情况下，它们是从Rust文件中执行的），它们将不会显示颜色。
有没有办法告诉 Command 以类似于在终端中直接执行命令的方式来执行命令？这样，我就不必每次执行命令时都启用颜色（使用标志）了吗？"
英文:
The following code defines custom terminal commands (KeyboardShortcut) and executes them:
use std::io::{stdout, Write};use std::process::Command;use termion::raw::IntoRawMode;struct KeyboardShortcut {key: char,description: &'static str,command: &'static str,}impl KeyboardShortcut {fn execute_command(&self, stdout: &mut impl Write) {Command::new("sh").arg("-c").arg(self.command).status();}}fn main() {let mut stdout = stdout().into_raw_mode().unwrap();// Do something in raw modelet keyboard_shortcuts = vec![KeyboardShortcut {key: 'f',description: "Feat: adds a new feature to the application",command: "ls --color=always",}];stdout.flush().unwrap();// In the actual application, I'm using `match`.keyboard_shortcuts[0].execute_command(&mut stdout)}
Notice that I had to add --color=always to the command. This is because commands won't display colors if they are not executed directly in the terminal (in this case, they are being executed from a Rust file).
Is there a way to tell Command to execute commands as if they were being executed directly in the terminal? So that I don't have enable colors (with flags) every time I want to execute a command?

替代在 `execute_command` 中用 `sh` 包装命令，改用 [`script`](https://man7.org/linux/man-pages/man1/script.1.html) 来包装，如下所示：```rustfn execute_command(&self, stdout: &mut impl Write) {Command::new("script").arg("-qec").arg(self.command).arg("/dev/null").status();}
附加的 .arg("/dev/null") 阻止 script 记录所有控制台输出，这实际上是其预期用途。
请注意，默认情况下 ls 不会以彩色打印 - 如果对您来说是彩色的，那是由于 shell 别名。不过，我们可以通过执行 ls --color=auto 来证明这个更改已经生效。
let keyboard_shortcuts = vec![KeyboardShortcut {key: 'f',description: "Feat: adds a new feature to the application",command: "ls --color=auto",}];
现在应该以彩色打印。

However we can prove this change worked by executing `ls --color=auto`.let keyboard_shortcuts = vec![KeyboardShortcut {key: 'f',description: "Feat: adds a new feature to the application",command: "ls --color=auto",}];Which should now print in colour.</details>
