运行非标准 cron 作业

操作系统：Ubuntu 14.04

我想在全年每周一至周五格林威治标准时间上午 5 点至下午 7 点之间每两小时第 37 分钟运行 PHP 脚本 /home/app/myapp.php。

crontab 文件的语法是什么？

答案1

37 5-19/2 * * 1-5

因为，引用手册页：

  field          allowed values
  -----          --------------
  ...
  day of week    0-7 (0 or 7 is Sun, or use names)

Ranges of numbers are allowed.  Ranges are two numbers separated with a hyphen.    
...    
Step  values  can be used in conjunction with ranges.  Following a range with ``/<number>'' specifies skips of the number's value through the range.

Names can also be used for the ``month'' and ``day of week'' fields.  ...  Ranges or lists of names are not allowed.
