/bin/sh: Syntax error: Unterminated quoted string
提问by oompahloompah
I am trying to get a cronjob to pipe output into a dated file in a specified (folder) location.
我正在尝试使用 cronjob 将输出通过管道传输到指定（文件夹）位置的过时文件中。
My crontab entry looks something like this:
我的 crontab 条目如下所示：
* * * * * /some/path/test.sh >> $(date "+/home/oompah/logs/%Y%m%d.test.log")
What I don't understand is that when I type this command at the console, I get the correct string:
我不明白的是，当我在控制台输入这个命令时，我得到了正确的字符串：
echo $(date "+/home/oompah/logs/%Y%m%d.test.log")
/home/oompah/logs/20110329.test.log
What's causing this error and how may I fix it?
是什么导致了这个错误，我该如何解决？

You should excape the percent signs in your crontab:
您应该在 crontab 中排除百分号：
* * * * * /some/path/test.sh >> $(date "+/home/oompah/logs/\%Y\%m\%d.test.log")
Percent (%) signs have a special meaning in crontabs. They are interpreted as newline characters.
百分比 ( %) 符号在 crontab 中具有特殊含义。它们被解释为换行符。

Put the date command inside the script. cronisn't necessarily running the shell you think it is.
将日期命令放在脚本中。cron不一定运行您认为的 shell。

make sure you have shebang #!/bin/bashas the first line in your script. Also, as bmarguliesstated, put the datecommand inside the script if possible.
确保您将shebang#!/bin/bash作为脚本中的第一行。另外，bmargulies如上所述，date如果可能，将命令放在脚本中。
