cron: sending output to file then EMAILing file to me
提问by oompahloompah
I am writing a series of cron jobs. I want each task to log its output to file, and then I want the contents of the file mailed to me at say [email protected]
我正在编写一系列 cron 作业。我希望每个任务都将其输出记录到文件中，然后我希望将文件的内容邮寄给我说 [email protected]
I think logging the output to file can be done using simple pipe redirection like this:
我认为可以使用像这样的简单管道重定向来将输出记录到文件中：
30 0 * * * /path/to/script1 > task1.log
30 1 * * * /path/to/script2 > task2.log
However, I am not sure how to mail the files (or simply their contents) to me in seperate emails to [email protected]
但是，我不确定如何通过单独的电子邮件将文件（或只是它们的内容）邮寄给 [email protected]
Also, is there a way to dynamically create the log file names, based on the date, so that the log names would be something like %Y%m%d.task1.log ?
另外，有没有办法根据日期动态创建日志文件名，以便日志名称类似于 %Y%m%d.task1.log ？
Where the prefix is the date ?
前缀是日期在哪里？

If your system has a working /usr/bin/sendmail(doesn't have to be sendmailsendmail, most mail servers provide a /usr/bin/sendmailwrapper script) then you can use the mail(1)utility to send mail:
如果您的系统有一个工作/usr/bin/sendmail（不必是sendmailsendmail，大多数邮件服务器提供/usr/bin/sendmail包装脚本），那么您可以使用该mail(1)实用程序发送邮件：
echo "hello world" | mail -s hello [email protected]
mail(1)is pretty primitive; there's no MIME file attachments, you're stuck with plaintext.
mail(1)很原始；没有 MIME 文件附件，您只能使用纯文本。
If mutt(1)is installed, you can use MIME to attach files:
如果mutt(1)已安装，则可以使用 MIME 附加文件：
echo "hello world" | mutt -a task*.log -- [email protected]
As for giving the logfiles dates:
至于给日志文件日期：
$ echo "hi" > $(date "+%Y%m%dlog.txt")
$ cat 20110328log.txt
hi
$
So, try this:
所以，试试这个：
30 1 * * * /path/to/script2 > $(date "+\%Y\%m\%dlog.txt") && mutt -a $(date "+\%Y\%m\%dlog.txt") -- [email protected]
