### Lambda 表达式
|
||||||
|
<!--rehype:wrap-class=col-span-2-->
|
||||||
|
|
||||||
|
Lambda 表达式可以在函数内定义,可以理解为在函数内定义的临时函数。格式:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
auto func = []() -> return_type { };
|
||||||
|
```
|
||||||
|
|
||||||
|
- `[]`为捕获列表,能够捕获其所在函数的局部变量
|
||||||
|
- 一个空的捕获列表代表Lambda表达式不捕获任何的变量
|
||||||
|
- 对于值捕获,直接在中括号中填写要捕获的变量即可:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
int val = 5;
|
||||||
|
auto func = [val]() -> return_type { };
|
||||||
|
```
|
||||||
|
|
||||||
|
- 对于引用捕获,需要在捕获的变量前添加`&`:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
string str("hello world!");
|
||||||
|
auto func = [&str]() -> return_type { };
|
||||||
|
```
|
||||||
|
|
||||||
|
- 如果变量太多,需要编译器根据我们编写的代码自动捕获,可以采用隐式捕获的方式。
|
||||||
|
|
||||||
|
- 全部值捕获:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
int val1, val2;
|
||||||
|
auto func = [=]() -> int
|
||||||
|
{
|
||||||
|
return val1 + val2;
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
- 全部引用捕获:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
string str1("hello"), str2("word!");
|
||||||
|
auto func = [&]() -> string
|
||||||
|
{
|
||||||
|
return str1 + str2;
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
- 混合隐式捕获:
|
||||||
|
|
||||||
|
如果希望对一部分变量采用值捕获,对其他变量采用引用捕获,可以混合使用:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
int val1 = 123, val2 = 456;
|
||||||
|
string str1("123"), str2(456);
|
||||||
|
|
||||||
|
auto func1 = [=, &str1]() -> int
|
||||||
|
{
|
||||||
|
return val1 == std::stoi(str1)
|
||||||
|
? val1 : val2;
|
||||||
|
};
|
||||||
|
|
||||||
|
auto func2 = [&, val1]() -> int
|
||||||
|
{
|
||||||
|
return str1 == std::to_string(val1)
|
||||||
|
? str1 : str2;
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
- `()` 是参数列表,我们只需要按照普通函数的使用方法来使用即可
|
||||||
|
- `return_type` 是函数的返回类型,`-> return_type` 可以不写,编译器会自动推导
|
||||||
|
- `{}` 中的内容就是函数体,依照普通函数的使用方法使用即可
|
||||||
|
<!--rehype:className=style-timeline-->
|
||||||
|
|
||||||
|
此处给出一个 Lambda 表达式的实际使用例子(当然可以使用 `str::copy`):
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
// vec中包含1, 2, 3, 4, 5
|
||||||
|
std::vector<int> vec({1, 2, 3, 4, 5});
|
||||||
|
std::for_each(vec.begin(), vec.end(),
|
||||||
|
[](int& ele) -> void
|
||||||
|
{
|
||||||
|
std::cout << ele
|
||||||
|
<< " ";
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
## C++多线程
|
||||||
|
|
||||||
|
### 多线程介绍
|
||||||
|
|
||||||
|
g++编译选项:`-std=c++11`。包含头文件:
|
||||||
|
|
||||||
|
- `#include <thread>`:C++多线程库
|
||||||
|
- `#include <mutex>`:C++互斥量库
|
||||||
|
- `#include <future>`:C++异步库
|
||||||
|
|
||||||
|
### 线程的创建
|
||||||
|
<!--rehype:wrap-class=row-span-2-->
|
||||||
|
|
||||||
|
以普通函数作为线程入口函数:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
void entry_1() { }
|
||||||
|
void entry_2(int val) { }
|
||||||
|
|
||||||
|
std::thread my_thread_1(entry_1);
|
||||||
|
std::thread my_thread_2(entry_2, 5);
|
||||||
|
```
|
||||||
|
|
||||||
|
以类对象作为线程入口函数:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
class Entry
|
||||||
|
{
|
||||||
|
void operator()() { }
|
||||||
|
void entry_function() { }
|
||||||
|
};
|
||||||
|
|
||||||
|
Entry entry;
|
||||||
|
// 调用operator()()
|
||||||
|
std::thread my_thread_1(entry);
|
||||||
|
// 调用Entry::entry_function
|
||||||
|
std::thread my_thread_2(&Entry::entry_function, &entry);
|
||||||
|
```
|
||||||
|
|
||||||
|
以lambda表达式作为线程入口函数:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
std::thread my_thread([]() -> void
|
||||||
|
{
|
||||||
|
// ...
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### 线程的销毁
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
thread my_thread;
|
||||||
|
// 阻塞
|
||||||
|
my_thread.join();
|
||||||
|
// 非阻塞
|
||||||
|
my_thread.detach();
|
||||||
|
```
|
||||||
|
|
||||||
|
### `this_thread`
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
// 获取当前线程ID
|
||||||
|
std::this_thread::get_id();
|
||||||
|
// 使当前线程休眠一段指定时间
|
||||||
|
std::this_thread::sleep_for();
|
||||||
|
// 使当前线程休眠到指定时间
|
||||||
|
std::this_thread::sleep_until();
|
||||||
|
// 暂停当前线程的执行,让别的线程执行
|
||||||
|
std::this_thread::yield();
|
||||||
|
```
|
||||||
|
|
||||||
|
### 锁
|
||||||
|
<!--rehype:wrap-class=row-span-3-->
|
||||||
|
|
||||||
|
> `#include <mutex>`
|
||||||
|
|
||||||
|
#### 锁的基本操作
|
||||||
|
|
||||||
|
创建锁
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
std::mutex m;
|
||||||
|
```
|
||||||
|
|
||||||
|
上锁
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
m.lock();
|
||||||
|
```
|
||||||
|
|
||||||
|
解锁
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
m.unlock();
|
||||||
|
```
|
||||||
|
|
||||||
|
尝试上锁:成功返回`true`,失败返回`false`
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
m.try_lock();
|
||||||
|
```
|
||||||
|
|
||||||
|
解锁
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
m.unlock();
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 更简单的锁 —— `std::lock_guard<Mutex>`
|
||||||
|
|
||||||
|
构造时上锁,析构时解锁
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
std::mutex m;
|
||||||
|
std::lock_guard<std::mutex> lock(m);
|
||||||
|
```
|
||||||
|
|
||||||
|
额外参数:`std::adopt_lock`:只需解锁,无需上锁
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
// 手动上锁
|
||||||
|
m.lock();
|
||||||
|
std::lock_guard<mutex> lock(m,
|
||||||
|
std::adopt_lock);
|
||||||
|
```
|
||||||
|
|
||||||
|
#### `unique_lock<Mutex>`
|
||||||
|
|
||||||
|
构造上锁,析构解锁
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
std::mutex m;
|
||||||
|
std::unique_lock<mutex> lock(m);
|
||||||
|
```
|
||||||
|
|
||||||
|
##### `std::adopt_lock`
|
||||||
|
|
||||||
|
只需解锁,无需上锁
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
// 手动上锁
|
||||||
|
m.lock();
|
||||||
|
std::unique_lock<mutex> lock(m,
|
||||||
|
std::adopt_lock);
|
||||||
|
```
|
||||||
|
|
||||||
|
##### `std::try_to_lock`
|
||||||
|
|
||||||
|
尝试上锁,可以通过`std::unique_lock<Mutex>::owns_lock()`查看状态
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
std::unique_lock<mutex> lock(m,
|
||||||
|
std::try_to_lock);
|
||||||
|
if (lock.owns_lock())
|
||||||
|
{
|
||||||
|
// 拿到了锁
|
||||||
|
}
|
||||||
|
else
|
||||||
|
{
|
||||||
|
// 没有
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
##### `std::defer_lock`
|
||||||
|
|
||||||
|
绑定锁,但不上锁
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
std::unique_lock<mutex> lock(m,
|
||||||
|
std::defer_lock);
|
||||||
|
lock.lock();
|
||||||
|
lock.unlock();
|
||||||
|
```
|
||||||
|
|
||||||
|
##### `std::unique_lock<Mutex>::release`
|
||||||
|
|
||||||
|
返回所管理的`mutex`对象指针,**释放所有权。**一旦释放了所有权,那么如果原来互斥量处于互斥状态,程序员有责任手动解锁。
|
||||||
|
|
||||||
|
#### `std::call_once`
|
||||||
|
|
||||||
|
当多个线程通过这个函数调用一个可调用对象时,只会有一个线程成功调用。
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
std::once_flag flag;
|
||||||
|
|
||||||
|
void foo() { }
|
||||||
|
|
||||||
|
std::call_once(flag, foo);
|
||||||
|
```
|
||||||
|
|
||||||
|
### `std::condition_variable`
|
||||||
|
|
||||||
|
#### 创建条件变量
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
std::condition_variable cond;
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 等待条件变量被通知
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
std::unique_lock<std::mutex>
|
||||||
|
lock;
|
||||||
|
extern bool predicate();
|
||||||
|
|
||||||
|
// 调用方式 1
|
||||||
|
cond.wait(lock);
|
||||||
|
// 调用方式 2
|
||||||
|
cond.wait(lock, predicate);
|
||||||
|
```
|
||||||
|
|
||||||
|
----
|
||||||
|
|
||||||
|
- `wait`不断地尝试重新获取并加锁该互斥量,如果获取不到,它就卡在这里并反复尝试重新获取,如果获取到了,执行流程就继续往下走
|
||||||
|
- `wait`在获取到互斥量并加锁了互斥量之后:
|
||||||
|
- 如果`wait`被提供了可调用对象,那么就执行这个可调用对象:
|
||||||
|
- 如果返回值为`false`,那么`wait`继续加锁,直到再次被 notified
|
||||||
|
- 如果返回值为`true`,那么`wait`返回,继续执行流程
|
||||||
|
- 如果`wait`没有第二个参数,那么直接返回,继续执行
|
||||||
|
|
||||||
|
#### `std::condition_variable::notify_one`
|
||||||
|
|
||||||
|
`notify_one` 唤醒一个调用 `wait` 的线程。注意在唤醒之前要解锁,否则调用 `wait` 的线程也会因为无法加锁而阻塞。
|
||||||
|
|
||||||
|
#### `std::condition_variable::notify_all`
|
||||||
|
|
||||||
|
唤醒所有调用 `wait` 的线程。
|
||||||
|
|
||||||
|
### 获取线程的运行结果
|
||||||
|
<!--rehype:wrap-class=row-span-2-->
|
||||||
|
|
||||||
|
> `#include <future>`
|
||||||
|
|
||||||
|
#### 创建异步任务
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
double func(int val);
|
||||||
|
|
||||||
|
// 使用std::async创建异步任务
|
||||||
|
// 使用std::future获取结果
|
||||||
|
// future模板中存放返回值类型
|
||||||
|
std::future<double> result =
|
||||||
|
std::async(func, 5);
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 获取异步任务的返回值
|
||||||
|
|
||||||
|
等待异步任务结束,但是不获取返回值:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
result.wait();
|
||||||
|
```
|
||||||
|
|
||||||
|
获取异步任务的返回值:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
int val = result.get();
|
||||||
|
```
|
||||||
|
|
||||||
|
注:
|
||||||
|
|
||||||
|
- `get()`返回右值,因此只可调用一次
|
||||||
|
- 只要调用上述任意函数,线程就会一直阻塞到返回值可用(入口函数运行结束)
|
||||||
|
|
||||||
|
#### `std::async` 的额外参数
|
||||||
|
|
||||||
|
额外参数可以被放在 `std::async` 的第一个参数位置,用于设定 `std::async` 的行为:
|
||||||
|
|
||||||
|
- `std::launch::deferred`:入口函数的运行会被推迟到`std::future<T>::get()`或者`std::future<T>::wait()`被调用时。此时调用线程会直接运行线程入口函数,换言之,**不会创建子线程**
|
||||||
|
- `std::launch::async`:立即创建子线程,并运行线程入口函数
|
||||||
|
- `std::launch::deferred | std::launch::async`:默认值,由系统自行决定
|
||||||
|
|
||||||
|
#### 返回值的状态
|
||||||
|
|
||||||
|
让当前线程等待一段时间(等待到指定时间点),以期待返回值准备好:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
extern double foo(int val) {}
|
||||||
|
|
||||||
|
std::future<double> result =
|
||||||
|
async(foo, 5);
|
||||||
|
|
||||||
|
//返回值类型
|
||||||
|
std::future_status status;
|
||||||
|
// 等待一段时间
|
||||||
|
status = result.wait_for(
|
||||||
|
std::chrono::seconds(1)
|
||||||
|
);
|
||||||
|
// 等待到某一时间点
|
||||||
|
status = result.wait_for(
|
||||||
|
std::chrono::now() +
|
||||||
|
std::chrono::seconds(1)
|
||||||
|
);
|
||||||
|
```
|
||||||
|
|
||||||
|
在指定的时间过去后,可以获取等待的结果:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
// 返回值已经准备好
|
||||||
|
if (status ==
|
||||||
|
std::future_status::ready)
|
||||||
|
{
|
||||||
|
|
||||||
|
}
|
||||||
|
// 超时:尚未准备好
|
||||||
|
else if (status ==
|
||||||
|
std::future_status::timeout)
|
||||||
|
{ }
|
||||||
|
// 尚未启动: std::launch::deferred
|
||||||
|
else if (status ==
|
||||||
|
std::future_status::deferred)
|
||||||
|
{ }
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 多个返回值
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
std::shared_future<T> result;
|
||||||
|
```
|
||||||
|
|
||||||
|
如果要多次获取结果,可以使用`std::shared_future`,其会返回结果的一个**拷贝**。
|
||||||
|
|
||||||
|
对于不可拷贝对象,可以在`std::shared_future`中存储对象的指针,而非指针本身。

### Proxy
|
||||||
|
|
||||||
|
Proxy 对象用于创建一个对象的代理,从而实现基本操作的拦截和自定义(如属性查找、赋值、枚举、函数调用等)。
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
// 用于拦截对象的读取属性操作。
|
||||||
|
const handler = {
|
||||||
|
get: function(obj, prop) {
|
||||||
|
return prop in obj ? obj[prop] : 37;
|
||||||
|
}
|
||||||
|
};
|
||||||
|
|
||||||
|
const p = new Proxy({}, handler);
|
||||||
|
p.a = 1;
|
||||||
|
p.b = undefined;
|
||||||
|
|
||||||
|
console.log(p.a, p.b); // 1, undefined
|
||||||
|
console.log('c' in p, p.c); // false, 37
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 语法
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
const p = new Proxy(target, handler)
|
||||||
|
```
|
||||||
|
|
||||||
|
- target 要使用 Proxy 包装的目标对象(可以是任何类型的对象,包括原生数组,函数,甚至另一个代理)。
|
||||||
|
- handler 一个通常以函数作为属性的对象,各属性中的函数分别定义了在执行各种操作时代理 p 的行为。

### Reflect
|
||||||
|
|
||||||
|
Reflect 是一个内置的对象,它提供拦截 JavaScript 操作的方法。这些方法与proxy handlers (en-US)的方法相同。Reflect不是一个函数对象,因此它是不可构造的。
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
// 检测一个对象是否存在特定属性
|
||||||
|
const duck = {
|
||||||
|
name: 'Maurice',
|
||||||
|
color: 'white',
|
||||||
|
greeting: function() {
|
||||||
|
console.log(`Quaaaack! My name is ${this.name}`);
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
Reflect.has(duck, 'color');
|
||||||
|
// true
|
||||||
|
Reflect.has(duck, 'haircut');
|
||||||
|
// false
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 静态方法
|
||||||
|
|
||||||
|
:- | :-
|
||||||
|
:- | :-
|
||||||
|
`Reflect.apply(target, thisArgument, argumentsList)` | 对一个函数进行调用操作,同时可以传入一个数组作为调用参数。和 Function.prototype.apply() 功能类似 [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/apply)
|
||||||
|
`Reflect.construct(target, argumentsList[, newTarget])` | 对构造函数进行 new 操作,相当于执行 new target(...args) [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/construct)
|
||||||
|
`Reflect.defineProperty(target, propertyKey, attributes)` | 和 Object.defineProperty() 类似。如果设置成功就会返回 true [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/defineProperty)
|
||||||
|
`Reflect.deleteProperty(target, propertyKey)` | 作为函数的delete操作符,相当于执行 delete target[name] [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/deleteProperty)
|
||||||
|
`Reflect.get(target, propertyKey[, receiver])` | 获取对象身上某个属性的值,类似于 target[name] [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/get)
|
||||||
|
`Reflect.getOwnPropertyDescriptor(target, propertyKey)` | 类似于 Object.getOwnPropertyDescriptor()。如果对象中存在该属性,则返回对应的属性描述符,否则返回 undefined [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/getOwnPropertyDescriptor)
|
||||||
|
`Reflect.getPrototypeOf(target)` | 类似于 Object.getPrototypeOf() [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/getPrototypeOf)
|
||||||
|
`Reflect.has(target, propertyKey)` | 判断一个对象是否存在某个属性,和 in 运算符 的功能完全相同 [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/has)
|
||||||
|
`Reflect.isExtensible(target)` | 类似于 Object.isExtensible() [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/isExtensible)
|
||||||
|
`Reflect.ownKeys(target)` | 返回一个包含所有自身属性(不包含继承属性)的数组。(类似于 Object.keys(), 但不会受enumerable 影响) [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/ownKeys)
|
||||||
|
`Reflect.preventExtensions(target)` | 类似于 Object.preventExtensions()。返回一个Boolean [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/preventExtensions)
|
||||||
|
`Reflect.set(target, propertyKey, value[, receiver])` | 将值分配给属性的函数。返回一个Boolean,如果更新成功,则返回true [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/set)
|
||||||
|
`Reflect.setPrototypeOf(target, prototype)` | 设置对象原型的函数。返回一个 Boolean,如果更新成功,则返回 true [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/setPrototypeOf)

ps 备忘清单
|
||||||
|
===
|
||||||
|
|
||||||
|
Linux 为我们提供了一个名为 `ps` 的实用程序,用于查看与系统上的进程相关的信息,它是 `Process Status` 的缩写
|
||||||
|
这份 `ps` 命令备忘清单的快速参考列表,包含常用选项和示例。
|
||||||
|
|
||||||
|
入门
|
||||||
|

|
||||||
|
|
||||||
|
### 语法
|
||||||
|
<!--rehype:wrap-class=row-span-4-->
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ ps [options]
|
||||||
|
```
|
||||||
|
|
||||||
|
命令运行示例,列出当前 shell 中的所有进程:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ ps
|
||||||
|
|
||||||
|
PID TTY TIME CMD
|
||||||
|
12330 pts/0 00:00:00 bash
|
||||||
|
21621 pts/0 00:00:00 ps
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
:-- | --
|
||||||
|
:-- | --
|
||||||
|
`PID` | 唯一的进程 ID
|
||||||
|
`TTY` | 用户登录的终端类型
|
||||||
|
`TIME` | 进程运行的 CPU 数量,以分钟和秒为单位
|
||||||
|
`CMD` | 启动进程的命令的名称
|
||||||
|
|
||||||
|
注意:有时当我们执行 `ps` 命令时,它显示 `TIME` 为 `00:00:00`
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
ps 命令支持 3 种使用语法风格
|
||||||
|
|
||||||
|
- `Unix` 可以分组并以连字符开头
|
||||||
|
- `BSD` 可以分组但前面没有连字符
|
||||||
|
- `GNU` 长选项,前面有双连字符
|
||||||
|
|
||||||
|

### 查看系统上的每个进程
|
||||||
|
|
||||||
|
要使用标准语法查看系统上的每个进程:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ ps -e # 列出所有进程
|
||||||
|
$ ps -ef
|
||||||
|
$ ps -eF
|
||||||
|
$ ps -ely
|
||||||
|
```
|
||||||
|
|
||||||
|
要使用 BSD 语法查看系统上的每个进程:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ ps ax # 以 BSD 格式列出所有进程
|
||||||
|
$ ps axu
|
||||||
|
```
|
||||||
|
|
||||||
|
### 打印进程树
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ ps -ejH
|
||||||
|
$ ps axjf
|
||||||
|
```
|
||||||
|
|
||||||
|
### 仅打印 PID 42 的名称
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ ps -q 42 -o comm=
|
||||||
|
```
|
||||||
|
|
||||||
|
### 获取有关线程的信息
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ ps -eLf
|
||||||
|
$ ps axms
|
||||||
|
```
|
||||||
|
|
||||||
|
### 列出当前用户拥有的所有进程
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ ps x
|
||||||
|
```
|
||||||

||||||
|
### 获取安全信息
|
||||||
|
<!--rehype:wrap-class=col-span-2-->
|
||||||
|
|
||||||

|
||||||
|
$ ps -eo euser,ruser,suser,fuser,f,comm,label
|
||||||
|
$ ps axZ
|
||||||
|
$ ps -eM
|
||||||
|
```
|
||||||
|
|
||||||
|
### 查看以 root 身份运行的每个进程
|
||||||
|
|
||||||
|
查看以 root 身份运行的每个进程(真实且有效的 ID)用户格式:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ ps -U root -u root u
|
||||||
|
```
|
||||||
|
|
||||||
|
### 查看具有用户定义格式的每个进程
|
||||||
|
<!--rehype:wrap-class=col-span-2-->
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ ps -eo pid,tid,class,rtprio,ni,pri,psr,pcpu,stat,wchan:14,comm
|
||||||
|
$ ps axo stat,euid,ruid,tty,tpgid,sess,pgrp,ppid,pid,pcpu,comm
|
||||||
|
$ ps -Ao pid,tt,user,fname,tmout,f,wchan
|
||||||
|
```
|
||||||
|
|
||||||
|
### 仅打印 syslogd 的进程 ID
|
||||||
|
|
||||||
