Mac/linux timed Run command line

If you want to start the operation, you can use the Mac's own Automator will run the command package into an app, and then in the user group "start at Login" list plus that app.

But you can't do that if you want to run it on a regular basis, using a command called crontab (or software?). ）

The practical instructions are only 3, very brief.

Edit a Scheduled Task list

Crontab-e

Show all Scheduled Tasks list

Crontab-l

Delete all Scheduled Tasks list

Crontab-r

And you can get through

crontab [file]

To put the configuration file in any location to crontab. As long as your files are legitimate text.

Like what

Crontab ~/autoscripts/.crontab

The exact configuration file format is also simple

Each row has 6 elements, the first 5 elements are time, and the order represents

Minute Hour month date week

Can be a number representing only that number, or "0-10" to indicate a period of time, or an asterisk (*) to indicate any time

Like what

* * * * * * Say hello

The delegate runs say hello at any time (i.e. every minute) on the console, that is, read out Hello

5 1 say fuckyou

It's a 5-point computer yelling "fuck♂you" every Monday morning.

6th element visible is the command to execute
