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

问题描述

我有一个快速问题。我需要添加一个cron到我的debain crontab使用自动化shell脚本，我需要cron做两件事：

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. 运行命令scrapy crawl

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

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

如何获得它也运行scrapy抓取命令？

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

推荐答案

您可以在单个crontab行中有多个命令。只需用分号隔开：

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 -
