Wait for all processes with a certain name to finish (in bash)

血红的双手。 提交于 2019-12-07 15:00:31
问题 I would like to wait in linux (Ubuntu 11.10) for a load of processes to finish. Each of these processes has a different pid but the same name. Is it possible to do this? EDIT: Perhaps I should specify that I don't necessarily know what the pid are, just the process name. EDIT: Thanks for the answers; Kevin's seems to do what I want. However, it doesn't work in the specific application I have, so I've posted a more detailed follow-up question here. 回答1: wait $(pgrep programName) Ought to do it

How to get PID via subprocess.Popen with custom environment variable?

一世执手 提交于 2019-12-07 13:41:27
问题 Using Python, how can I run a subprocess with a modified environment variable and get its PID? I assume subprocess.Popen() is along the right track... In shell (bash), I would do this: MY_ENV_VAR=value ./program_name arg1 arg2 etc & This runs program_name in the background, passing in "arg1" and "arg2" and "etc", with a modified environment variable, "MY_ENV_VAR" with a value of "value". The program program_name requires the environment variable MY_ENV_VAR to be set to the proper value. How

windows 根据端口查看进行PID 并杀掉进程

1. 首先用netstat -ano | find “端口号”查出进程号 明明有端口号是17568和18892, 如何确定是17568呢 2. takslist 查询当前的进行 3. 如何杀死进程呢 tasklist /pid ${xx} 发现不行呢,权限不够,用管理员权限运行cmd,发现又报错了,说要强制执行才可以,加上-F 总结下: taskkill是Windows命令行里终止指定程序“进程”的命令。 /f 表示强制终止 /im 表示指定的进程名称,例如“explor.exe" /pid 表示指定的进程ID进程号 taskkill /f /im javaw.exe taskkill /f /pid 3352 ? 1 2 3 4 5 6 7 8 9 10 11 总结下: taskkill是Windows命令行里终止指定程序“进程”的命令。 /f 表示强制终止 /im 表示指定的进程名称,例如“explor.exe" /pid 表示指定的进程ID进程号 taskkill /f /im javaw.exe taskkill /f /pid 3352   windows批处理删除指定进程 ? 1 2 3 4 5 6 7 8 9 10 11 12 13 @ echo off setlocal enabledelayedexpansion set /p port=请输入端口号: for

原因: 端口被占用。 解决方法: 首先要检查是你需要的端口比如:3306,被哪个程序占用了,方法如下: 1、开始---->运行---->cmd,或者是window+R组合键,调出命令窗口 2、输入命令:netstat -ano,列出所有端口的情况。在列表中我们观察被占用的端口,比如是3306,首先找到它。 3、查看被占用端口对应的PID,输入命令:netstat -aon|findstr "3306",回车,记下最后一位数字,即PID,这里是2720(这里的PID只是举例说明,要查询到自己对应的PID才可以) 4、继续输入tasklist|findstr "2720",回车,查看是哪个进程或者程序占用了2720端口,结果是:svchost.exe 5、或者是我们打开任务管理器,切换到进程选项卡,在PID一列查看2720对应的进程是谁 6、找到以后,结束该进程就可以了。 来源: https://www.cnblogs.com/zhengdongdong/p/12001152.html

Are process IDs assigned sequentially in Linux?

泪湿孤枕 提交于 2019-12-07 10:34:48
问题 If a program has a process ID of P, will the child processes (and their children) have process IDs which are strictly greater then P? When process IDs are reused, which process IDs are chosen e.g., is the lowest process ID available? 回答1: From http://en.wikipedia.org/wiki/Process_identifier Process IDs are usually allocated on a sequential basis, beginning at 0 and rising to a maximum value which varies from system to system. Once this limit is reached, allocation restarts at 300 and again

ubuntu 下 启动mysql 服务 出现 The server quit without ...

这个错误是如何产生的呢? 启动mysql 为什么会报 The server quit without updating PID file(....pid ) 产生的原因有几种, 1:配置文件出现错误my.cnf 2:/usr/local/mysql/data 文件夹 的权限问题 3:进程已存在 mysql 的服务 首先 说说楼主的遭遇, 由于 配置 mysql 默认编码格式的时候出现配置错误, 导致 启动mysql (后来才想起来 我改过配置文件了) The server quit without updating PID file(updat file .....pid ) 悲催的折腾到2点多,google 查各种资料..于是便有了上面几个总结 问题1 的解决: 由于我当时脑抽了估计,居然改/usr/local/mysql/my.cnf 配置文件,导致后来才发现这里改动过了, 但是mysql 启动的时候,我觉得应该是这样进行查找my.cnf 的 首先 /etc/my.cnf 是否存在 if( true): 读取/etc/my.cnf else: 读取/usr/local/mysql/my.cnf | /usr/local/mysql/my.cnf~ 检查发现 my.cnf 没问题,于是问题1 忽略( 结果就是折腾到2点,忽略了/usr/local/mysql/my.cnf 的检查

Bash: start remote python application through ssh and get its PID

纵然是瞬间 提交于 2019-12-07 01:26:38
问题 I'm creating a little bash script to copy new files from a windows machine to a remote linux centos server (i run this script using the git-shell) then i want to restart the python application thats running in the server to use those new files. The problem is that everytime i run this script i want to end the actual running process before i start it again, so i want to get the pid of the process i start and save it to a file in the remote host so i can read it from there the next time i run

Is there a way to determine if a Linux PID is paused or not?

北城余情 提交于 2019-12-07 01:04:43
问题 I have a python script that is using the SIGSTOP and .SIGCONT commands with os.kill to pause or resume a process. Is there a way to determine whether the related PID is in the paused or resumed state? 回答1: You can find information about a process from its /proc directory ( /proc/<PID> ). Specifically, you can find its run state with this python expression: open(os.path.join('/proc', str(pid), 'stat')).readline().split()[2]=='T' EDIT: This next expression fixes a (presumably rare) bug with the
