linux下读取文件路径怎么写

cat /path/to/your/file.txt

less /path/to/your/largefile.txt

more /path/to/your/largefile.txt

file_path = "/path/to/your/file.txt"
with open(file_path, 'r') as file:
    content = file.read()
    print(content)

import java.io.FileReader;
import java.io.IOException;

public class ReadFile {
    public static void main(String[] args) {
        String filePath = "/path/to/your/file.txt";
        try (FileReader fr = new FileReader(filePath)) {
            int content;
            while ((content = fr.read()) != -1) {
                System.out.print((char) content);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

#include <iostream>
#include <fstream>
#include <string>

int main() {
    std::string filePath = "/path/to/your/file.txt";
    std::ifstream file(filePath);
    if (file.is_open()) {

        while (getline(file, line)) {
            std::cout << line << std::endl;
        }
        file.close();
    } else {
