Cron jobs from a terminal

[GlassFish]

Hello everyone
I want to create cron jobs from a terminal only space here is what I would do.
Identify each task by a single file of ways to edit, remove easily. I have searched, looked at the manual. I hear good file but not how to create / edit. I also thought and think this is how I do (I prefer to wait for a notice before testing) Create a file "/ var / spool / cron"Appointed"cron_ * id *. cron" with this content. Then execute the command "crontab / var / spool / cron / cron_ * id *. cron. Thanks in advance.

Hi,
In my opinion it should take to reverse your problem. This can give something like this:

0 0 1 * * my_command

The file my_command might be this:

/ bin / bash
cmd-1
cmd-2
...

The file must be executable my_command course. This file is easily editable via a text editor to add / remove command. I believe that this approach solves your problem and is cleaner than what you initially planned. Each line of the file my_command may be the name of a script of course.

Hi
Indeed I understand this system. The base was to administer the tasks from an administration interface. But I think I'm going to use this file to add / delete / edit tasks by doing this: (in php / shell)

- Listing of crontab (shell)
- Viewing and Editing (php)
- Update / Add / Supprission (shell)

I just wanted to create a file but a unique name for each task in a very specific file easily manage (delete, add and delete / add to change) these tasks but it will have "push" a little system.
If anyone knows a simpler method, please do post.

Hi,
Nothing prevents you to do it like that. you can retrieve all file names and concatenate them into a file (executable of course). This file is the only existing line in your crontab. So once your set up spot in crontab not need to touch it. Updated fairly easy with a simple shell script. Hope this may help you.
