使用 crontab 运行两个命令 [英] Run two commands with a crontab

问题描述

我有一个简单的问题.我需要使用自动 shell 脚本将 cron 添加到我的 debain crontab 中，并且我需要 cron 来做两件事:

1. cd 进入/etc/application
2. 运行命令scrapy crawl"

<块引用>

crontab -l |{/bin/cat;/bin/echo "* 3 * * * cd/etc/application";}|crontab -

如何让它也运行 scrapy crawl 命令?

解决方案

您可以在单个 crontab 行中包含多个命令.只需用分号分隔它们:

crontab -l |{/bin/cat;/bin/echo "* 3 * * * cd/etc/application ; scrapy crawl";} |crontab -

I have a quick question. I need to add a cron to my debain crontab using an automated shell script and I need the cron to do two things:

1. cd into /etc/application
2. run the command "scrapy crawl"

crontab -l | { /bin/cat; /bin/echo "* 3 * * * cd /etc/application"; } | crontab -

How do I get it to also run the scrapy crawl command?

解决方案

You can have multiple commands in a single crontab line. Just separate them with semicolons:

crontab -l | { /bin/cat; /bin/echo "* 3 * * * cd /etc/application ; scrapy crawl"; } | crontab -
