crontab command not found in my git-bash for windows 7

I cannot use crontab -e in my git that I installed it in my pc windows 7. It produced the error bash: crontab: command not found Did someone use to do it, please tell me? VonC I confirm that even the latest git for windows (2.6.3) with its 4.3.42(3)-bash does not include any cron command. You would need to use another "cron from Windows" , like the official Microsoft command Schtasks.exe . 来源: https://stackoverflow.com/questions/33775581/crontab-command-not-found-in-my-git-bash-for-windows-7

问题 Are PHP scripts run using the "php" command affected by the timeout limit? I plan to schedule php scripts using cron. 回答1: Yes, but you can set an unlimited timeout by adding this to the top of your script: set_time_limit(0); 回答2: Some systems, such as Ubuntu, actually already start with separate CLI and Apache configurations in /etc/php5 . The relevant command in the ini file is: max_execution_time = 30 ; Maximum execution time of each script, in seconds However, if you are unable to modify

Is there a tool that allows visualization of crontab entries? [closed]

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I have crontabs for many machines, and wanted to see what started when, and to ensure load on the database server would be fine. Is there a tool that either converts crontab entries to iCal, or a tool that directly does visualization? 回答1: I don't have a great cron specific answer for this but in case its

replace crontab file with -e

问题 Anyone know a way to give a file into crontab -e ? I cannot use the regular form of crontab giving it a path but still need to replace the whole contents. Perhaps setting EDITOR to something? 回答1: You can source cron jobs from a file into your crontab using crontab /path/to/cron/file/name To make it more explicit for readability's sake, use the arrow < for sourcing. crontab < /path/to/cron/file/name Sourcing the cron jobs this way can throw error errors in crontab file, can't install in case

Cronjobs in Docker container how get them running?

早过忘川 提交于 2019-12-04 17:35:51
I've got some cronjobs in my debian docker container. They don't start automatically why? Do I have to do some workarounds? If you are running containers in docker, you can add cron tasks on the docker host machine to execute commands in the docker containers. For example, to run 'stress' application in your container every 5 minutes you can add the following (substituting your container ID of course) to your crontab: */5 * * * * docker exec c78ddbed4ad9 /bin/sh -c 'stress -d 1 --hdd-bytes 64M --cpu 1 --io 2 --vm 2 --vm-bytes 64M --timeout 60s' >> /tmp/cronstress.log 2>&1 I am running this as

linux下crontab命令的使用技巧

在 Linux 中任务可以被配置在指定的时间段、指定的日期、或系统平均载量低于指定的数量时自动运行。 crontab 是一个很方便的在unix/ linux 系统上定时(循环)执行某个任务的程序。 cron服务是可以根据时间、日期、月份、星期的组合来调度对重复任务执行的守护进程。linux的cron服务是每隔一分钟去读取一次/var/spool/cron,/etc/ crontab ,/etc/cron.d下面所有的内容。 crond服务通常被放在/etc/init.d/crond , 这样就可以在系统启动后自动启动crond服务。 linux中的用户使用crontab命令来配置cron任务. crontab在/etc目录下面存在cron.d,cron.daily,cron.weekly,cron.monthly,cron.hourly五个目录和crontab文件。 cron.d是系统自动定期需要做的任务,但是又不是按小时,按天,按星期,按月来执行的,那么就放在这个目录下面。 如果是 按小时,按天,按星期,按月的来执行 的话,则可以放到相应的目录下面去。 cron.hourly是每个小时执行一次的任务 cron.daily是每天执行一次的任务 cron.weekly是每个星期执行一次的任务 cron.monthly是每月执行一次的任务 Linux下的Crontab使用详解

php利用crontab执行 5分钟发邮件给用户 (包含每分钟发一次)

php利用crontab执行 5分钟发邮件给用户 一开始设想用shell_exec执行sh 运行 crontab但发现并不可取 因为没办法传变量 (因为要传963529987@qq.com) 所以决定采用 1 发邮件 直接insert into到数据库 2 shell里面写个定时器 php代码就是每秒读取数据库的变化 来决定执行 (只要有1个字段来判断是否执行过就行了) 如果10分钟 就update字段 应该发的时间 这个时候每秒判断有没有到这个时间就行了 上面是发一次 下面说每分钟发一次的写法 这个地方还要再写个定时器每秒触发一次的 1 写入每分钟要发的用户信息 2 读取触发 (判断触发依据 当前时间减去 刚开始的时间 除以600000 看看是不是等于0) 3 如果要取消 直接删除数据库表的用户信息 ps:swoole里的定时器或许可以试试 来源: https://www.cnblogs.com/newmiracle/p/11871347.html
