On every modern linux distribution you have the cronutility. This tool allow you to schedule tasks regularly (or not).
在每个现代 linux 发行版上，您都有该cron实用程序。此工具允许您定期（或不定期）安排任务。
To schedule your task, you have to launch crontaband then, inside the file presented (which is the list of your scheduled tasks), put something like this :
要安排您的任务，您必须启动crontab，然后在显示的文件（这是您的计划任务列表）中输入如下内容：
0 * * * * /absolute/path/to/your/parseScript.sh
This will launch every hour at 0minute (so, at 0:00, 1:00, 2:00....) your script (give the absolute path of your script)
这将每小时每0分钟启动一次（因此，在 0:00、1:00、2:00....）您的脚本（给出脚本的绝对路径）
With very last versions of cron, you can even use something easier :
使用最新版本的 cron，您甚至可以使用更简单的东西：
@hourly /absolute/path/to/your/parseScript.sh
Because new shortcuts have been implemented (@hourly, @daily, @weekly, @monthly...)
因为已经实施了新的快捷方式（@hourly、@daily、@weekly、@monthly...）

this solution:
这个解决方案：
$watch --interval=3600 command
No sudoer user, no config, ideal for just use from time to time as a dirty solution.
没有 sudoer 用户，没有配置，非常适合偶尔用作肮脏的解决方案。
Also, you can cancel that execution whenever you want
此外，您可以随时取消该执行
