Question

基于给定文件test.txt的信息，我希望得到一个pid及其可执行路径，用于对该文件进行操作的进程。

例如，如果从命令行有人运行了这个：

$ cat test.txt

...然后我想要一些能够提供与此类似的输出的东西：

process 1123 bin/cat is using /home/sam/test.txt

如果文件仍处于打开状态，您可以使用：

function CollegeDepartment() {
    var s1 = document.getElementById("college");
    var s2 = document.getElementById("department");
    s2.innerHTML = "";
    if (s1.value == "College of Engineering") {
        var optionArray = ["Civil Engineering", "Computer Engineering", "Electrical Engineering", "Electronics and Communication Engineering", "Industrial Engineering", "Mechanical Engineering"];
    } else if (s1.value == "CAS") {
        var optionArray = ["Political Science", "Mascomm", "Liacomm"];
    } else if (s1.value == "Commerce") {
        var optionArray = ["Business Ad", "Hotel Management", "Tourism"];
    } else if (s1.value == "Education") {
        var optionArray = ["SPED"];
    } else if (s1.value == "CICCT") {
        var optionArray = ["Computer Science", "Information Technology"];
    }

    for (var option in optionArray) {
        var newOption = document.createElement("option");
        newOption.value = optionArray[option];
        newOption.innerHTML = optionArray[option];
        s2.options.add(newOption);
    }
};

如何通过此pid执行的文件获取pid及其可执行路径信息？
