Cron作业stderr到电子邮件和日志文件？ [英] Cron job stderr to email AND log file?

问题描述

我有一个cron工作：

I have a cron job:

$SP_s/StartDailyS1.sh >$LP_s/MirrorLogS1.txt

其中 SP_s 是脚本的路径， LP_s 是日志文件的路径。这会将stdout发送到日志文件，并将stderr发送到我的电子邮件。

Where SP_s is the path to the script and LP_s is the path for the log file. This sends stdout to the log file and stderr to my email.

我如何？

1）将stdout和stderr同时发送到日志文件，

2）AND send stderr以电子邮件

How do I?:
1) send both stdout AND stderr to the logfile,
2) AND send stderr to email

或换句话说：stderr同时记录日志文件和电子邮件，stdout只记录到日志文件。

or to put it another way: stderr to both the logfile and the email, and stdout only to the logfile.

更新：
我到目前为止的答案都没有遵循我列出的或者似乎适合CRON作业的标准。

UPDATE: None of the answers I've gotten so far either follow the criteria I set out or seem suited to a CRON job.

我看到了，这是意在将STDOUT和STDERR从命令发送到一个文件，然后只是STDERR到另一个文件（由zazzybob在unix.com上发布），这似乎接近我想做的，我想知道是否会激励别人比我更聪明：

I saw this, which is intended to "send the STDOUT and STDERR from a command to one file, and then just STDERR to another file" (posted by zazzybob on unix.com), which seems close to what I want to do and I was wondering if it would inspire someone more clever than I:

(( my_command 3>&1 1>&2 2>&3 ) | tee error_only.log ) > all.log 2>&1 

我希望cron将STDERR发送到电子邮件， '。

I want cron to send STDERR to email rather than 'another file'.

推荐答案

由于我只是看着T恤的信息页（试图找出如何做同样的事情）

Since I was just looking at the info page for tee (trying to figure out how to do the same thing), I can answer the last bit of this for you.

这是大部分的方式：

(( my_command 3>&1 1>&2 2>&3 ) | tee error_only.log ) > all.log 2>&1

，但将error_only.log替换为>（email_command）

but replace "error_only.log" with ">(email_command)"

(( my_command 3>&1 1>&2 2>&3 ) | tee >(/bin/mail -s "SUBJECT" "EMAIL") ) > all.log 2>&1

注意：根据tee的文档，这将工作在bash，不在/ bin / sh中。如果你把这放在一个cron脚本（如/etc/cron.daily/），那么你可以只是＃！/ bin / bash在顶部。然而，如果你把它作为一个线索在crontab然后你可能需要将它包装在bash -c

Note: according to tee's docs this will work in bash, but not in /bin/sh. If you're putting this in a cron script (like in /etc/cron.daily/) then you can just but #!/bin/bash at the top. However if you're putting it as a one-liner in a crontab then you may need to wrap it in bash -c ""
