pid

1.创建shell脚本 touch /data/image/deamon.sh vi /data/image/deamon.sh 　　拷贝脚本 #!/bin/bash test(){ while true do echo `date` >> /data/image/log.txt sleep 5 done } case $1 in start) path="/root/shouhu.pid" if [ -f $path ]; then pid=`cat /data/image/deamon.pid` echo "pid $pid running..." else test & echo $! > /data/image/deamon.pid echo "running $!..." fi ;; stop) pid=`cat /data/image/deamon.pid` if [ -z pid ] then kill -9 $pid echo "stop $pid..." rm -rf /data/image/deamon.pid fi ;; restart) path="/data/image/deamon.pid" if [ -f "$path" ];then pid=`cat /data/image/deamon.pid` kill -9 $pid echo " stop

php无限极分类 今天琢磨了好久，现在想想除了更加深沉的意识到自己身上的不足之外，毫无收获，垂头丧气的感觉真真确确迎面而来 其实啊，网上遍地都是，，傻傻的我，还是在这里做下笔记，搜到了先放这里，后面会再测试的，， 案例一 <?php $arr = array( array('id'=>1,'name'=>'电脑','pid'=>0), array('id'=>2,'name'=>'手机','pid'=>0), array('id'=>3,'name'=>'笔记本','pid'=>1), array('id'=>4,'name'=>'台式机','pid'=>1), array('id'=>5,'name'=>'智能机','pid'=>2), array('id'=>6,'name'=>'功能机','pid'=>2), array('id'=>7,'name'=>'超级本','pid'=>3), array('id'=>8,'name'=>'游戏本','pid'=>3), ); function demo($arr,$id,$level) { $list =array(); foreach ($arr as $k=>$v){ if ($v['pid'] == $id){ $v['level']=$level; $v['son'] = demo($arr,$v['id'],$level

public function treeLevel(array $data, int $pid = 0, string $html = ‘–’, int $level = 0) { static a r r = [ ] ; f o r e a c h ( arr = []; foreach ( a r r = [ ] ; f o r e a c h ( data as KaTeX parse error: Expected '}', got 'EOF' at end of input: … if ( pid == $val[‘pid’]) { // 重复一个字符多少次 v a l [ ′ h t m l ′ ] = s t r r e p e a t ( val['html'] = str_repeat( v a l [ ′ h t m l ′ ] = s t r r ​ e p e a t ( html, $level * 2); $val[‘level’] = $level + 1; $arr[] = $val; t h i s − > t r e e L e v e l ( this->treeLevel( t h i s − > t r e e L e v e l ( data, $val[‘id’], $html, $val[‘level’]); } } return

netstat -aon|findstr "9090" 查找端口占用进程 tasklist|findstr "8224" 根据pid查找占用方式 taskkill /f /t /im javaw.exe或者 taskkill /pid 8224 /F 结束进程 备注：至于我第一个命令没好使，可能没配置java的环境变量？？?有时间在查吧！！！！！！！！！！ 来源： https://www.cnblogs.com/cuteCoderSnow/p/11416290.html

列表转换成树形结构方法定义： //javascript 树形结构 function toTree(data) { // 删除 所有 children,以防止多次调用 data.forEach(function(item) { delete item.children; }); // 将数据存储为 以 id 为 KEY 的 map 索引数据列 var map = {}; data.forEach(function(item) { // 在该方法中可以给每个元素增加其他属性 item.text = item.name; map[item.id] = item; }); // console.log(map); var val = []; data.forEach(function(item) { // 以当前遍历项，的pid,去map对象中找到索引的id var parent = map[item.pid]; // 好绕啊，如果找到索引，那么说明此项不在顶级当中,那么需要把此项添加到，他对应的父级中 if (parent) { // 可以给每个父节点添加属性 parent.iconCls = "i-folder"; // 添加到父节点的子节点属性中 (parent.children || (parent.children = [])).push(item); } else { /

I've a somewhat silly question, if i have a series of processes that are created ... these are not necessarily some sort of inheritance, the pid of the processes have to be numbers continuous or random pids ? This is determined by the Operating System. In general, they are usually sequentially assigned by the OS. However, this behavior is not something to base decisions upon, since most operating system specifications state that the process ID allocation is not deterministic (ie: it could be random, and could change in a future version, etc). On Linux, pids are generally allocated sequentially

对话级多任务 进程级 多任务 进程是运行中的程序 pid_t getpid();//返回当前进程得PID pid_t getppid();//返回父进程PID task_struct结构体是一个进程存在的唯一标示， 也就是进程控制块。PCB struct task_struct *task[512] ={&init_task}; 指针数组 pid hash数组 帮助管理进程PID fork();创建一个新的进程 #include<unistd.h> pit_t fork(void); 函数返回值：在父进程中创建返回的是子进程得PID号； 在子进程中返回的是0 ，创建失败返回-1 线程级 多任务 来源： http://www.cnblogs.com/yuankaituo/p/4236728.html

I am trying to detect when particular applications are launched. Currently I am using NSWorkspace , registering for the "did launch application" notification. I also use the runningApplications method to get apps that are currently running when my app starts. For most apps, the name of the app bundle is enough. I have a plist of "known apps" that I cross check with the name of that passed in the notification. This works fine until you come across an app that acts as a proxy for launching another application using command line arguments. Example: The newly released Portal on the Mac doesn't
