PHP on a windows machine; Start process in background

问题 I'm looking for the best, or any way really to start a process from php in the background so I can kill it later in the script. Right now, I'm using: shell_exec($Command); The problem with this is it waits for the program to close. I want something that will have the same effect as nohup when I execute the shell command. This will allow me to run the process in the background, so that later in the script it can be closed. I need to close it because this script will run on a regular basis and

linux环境下nohup的执行jar

java -jar XXX.jar & 命令结尾没有 “&” ，则变成 “java -jar XXX.jar ” ，表示在当前ssh窗口，可按CTRL + C打断程序运行，或者直接关闭窗口，则程序直接退出 命令结尾添加 “&” ，则变成 “java -jar XXX.jar &” ，表示在当窗口关闭时，程序才会中止运行。&代表让该命令在后台执行。 nohup java -jar XXX.jar > Log.log & 或者 nohup java -jar XXX.jar >> Log.log & 命令 “nohup java -jar XXX.jar &” 部分，表示不挂断运行命令,当账户退出或终端关闭时,程序仍然运行。注意，该作业的所有输出被重定向到nohup.out的文件中。 命令 “nohup java -jar XXX.jar > Log.log &” 部分，表示不挂断运行命令,当账户退出或终端关闭时,程序仍然运行，并且该作业的所有输出被重定向到Log.log的文件中。“ > Log.log ” 该命令就是指定日志输出的文件。 ">>"表示将输出以追加的方式重定向到Log.log中。 nohup java -jar XXX.jar > Log.log 2>&1 & 或者 nohup java -jar XXX.jar >> Log.log 2>&1 & 或者 nohup

shell 编程补充

1 反引号可以进行命令的执行 ，如 `pwd` 会执行pwd这个命令。也可以通过$(pwd)来执行 2 $0 代表当前命令本身的路径。 3 dirname 可以读取指定路径名，并删除最后一个斜杠后的路径。比如有 dirname /opt/apps ，结果为 /opt 4 `dirname "$0" `来获取当前脚本的目录。 5 位置参数可以用 shift 命令左移。比如 shift 3 表示原来的 $4 现在变成 $1 ，原来的 $5 现在变成 $2 等等，原来的 $1 、 $2 、 $3 丢弃， $0 不移动。不带参数的 shift 命令相当于 shift 1 。 这样我们来获取参数的时候就不用一个一个数了。 6 nohup 不挂端的运行，即脱离终端运行，当我们以当前shell启动了一个命令，如果shell关闭后，那么命令就不执行了，nohup可以解决这个问题 7 & 使命令在后台运行，一般与nohup组合使用。 nohup sh commnd & 8 变量定义的等号前后不要有空格 9 ${param1:-param2} , 如果param1不为空，结果为param1, 否则为param2 10 sh -c "cmd" 可以直接执行字符串内的命令 11 使用grep 来执行进行if判断： if grep qwrewq -q info.log ;then echo 'success

Bash script that will survive disconnection, but not user break

由 荒凉一梦 提交于 2019-12-25 11:57:27
问题 I want to write a bash script that will continue to run if the user is disconnected, but can be aborted if the user presses Ctrl+C. I can solve the first part of it like this: #!/bin/bash cmd=' #commands here, avoiding single quotes... ' nohup bash -c "$cmd" & tail -f nohup.out But pressing Ctrl+C obviously just kills the tail process, not the main body. Can I have both? Maybe using Screen? 回答1: I want to write a bash script that will continue to run if the user is disconnected, but can be

Running a JMeter script with nohup

问题 For the first time I'm just playing around with nohup on top of an Ubuntu server. I read few docs about nohup and got to know about the running commands with options such as nohup ./server.sh & . What I want to know is that, how should I be running the JMeter script (in headless mode) using nohup ? Following is the script I needed to run with nohup : ./jmeter.sh -n -t /home/chamith/WSO2MB/new/apache-jmeter-2.13/bin/GamesSubscriber.jmx When I tried using the normal nohup operation within the

Put php file in the background on Linux

问题 I have a PHP file that checks if a field in MySQL database is empty. If the field is empty, PHP is an update. I want to color this file in the background on Linux. If a user creates a record, the PHP file in the background will be updated. My PHP code: <?php $mysqli = mysqli_connect("localhost","name","pass","database"); $query = 'UPDATE users SET permissions = "content" WHERE permissions = ""'; $n = $mysqli->query($query); $query = "SELECT * from users"; $result = $mysqli->query($query);
