## auto-jobs

### Instructions

In this exercise you will create different files `task1`, `task2`, `task3`, `task4` containing the formulas required for setup a group of  Scheduled tasks in the group.

##### task1:
Time: `Every Friday, at 20:41`
Command: `echo "01"`

##### task2:
Time: `Every minute`
Command: `sh /home/user01/check`

##### task3:
Time: `Everyday midnight at 12 AM`
Command: `sh /home/user01/backup`

##### task4:
Time: `After Every Reboot`
Command: `01exec`

All files content must be in this format:

```console
$ cat task-example | cat -e
* * * * * {command}$
$
```

Once it is done, use the command below to create the file `auto-jobs.tar` to be submitted.

```console
$ tar -cf auto-jobs.tar task1 task2 task3 task4
$ ls
task1 task2 task3 task4 auto-jobs.tar
```

**Only `auto-jobs.tar` should be submitted.**
### Hints

Linux Cron utility is an effective way to schedule a routine background job at a specific time and/or day on an on-going basis.

You can use the `crontab` command to manage your jobs. This command can be called in four different ways:

`crontab -l`: List the jobs for the current user
`crontab -r`: Remove all jobs for the current users.
`crontab -e`: Edit jobs for the current user.
##### Linux Crontab Format:

`MIN HOUR DOM MON DOW CMD`

##### Examples:

1. Schedule a job every hour at the fifth minute, every day: `5 * * * * {command}`


2. Schedule a job 5 minutes after midnight every day: `5 0 * * * {command}`
