将Cron转换为已启动-MAILTO [英] Converting cron to launchd - MAILTO

问题描述

从旧Mac迁移到新Mac.

Migrating from an old mac to a new one.

尝试迁移旧Mac上的用户crontab.

Trying to migrate the user crontab I had on the old mac.

现在，我知道我可以通过创建/etc/crontab来使cron运行-但考虑到苹果已经弃用了cron，因此建议使用launchd-我想我应该将crontab迁移到启动的plist文件中.总是很高兴学习新东西:)

Now I know I can probably get cron to run by creating /etc/crontab - but given that apple has deprecated it in favour of launchd - I thought I'd take a swing at migrating my crontab to launchd plist files. Always fun to learn something new :)

crontab并不难-我倾向于设置可以完成工作的shell脚本，然后只在计划的时间调用它们.

The crontab isn't that hard - I tend to set up shell scripts that do the work and then just call them at scheduled times.

我可以同时从plist中调用这些命令-没问题.

I can call these fine from the plist at the same times - no issues.

但是-在我的crontab的顶部，我有MAILTO = my-gmail-email-address-因此，与其在框的邮件后台处理中向本地用户发送邮件，不如将其发送给gmail.

But - at the top of my crontab I had MAILTO=my-gmail-email-address - so that instead of sending mail to the local user on the box's mail spool it sent them to gmail for me.

我看不到您可以为启动的plist文件配置它.

I can't see that you can configure this for a launchd plist file.

那么-在我修改所有脚本以将所有输出重定向到tmp文件然后邮寄tmp文件之前(必须在很多脚本中这样做)，有没有办法在启动级别上做到这一点? /p>

So - before I go modify all my scripts to redirect all output to tmp files then mail the tmp file (would have to do this in quite a few scripts) - is there a way to do this at the launchd level?

推荐答案

恐怕launchd(8)不支持开箱即用地发送stdout/stderr.解决方法:

I'm afraid launchd(8) does not support mailing of stdout/stderr out of the box. Here's a workaround:

通过StandardOutPath和StandardErrorPath将输出重定向到专用目录中的文件.然后设置一个作业，以邮寄该目录中的每个文件.用QueueDirectories键触发此作业.确保此脚本在邮寄文件后将其删除.

Redirect output via StandardOutPath and StandardErrorPath to files in a dedicated directory. Then setup a job which mails every file in this directory. Trigger this job with the QueueDirectories key. Make sure this script removes the files after mailing them.
