## auto-jobs
### Instructions
In this exercise, you will create four files called `task1` , `task2` , `task3` , and `task4` , which will contain the necessary formulas to set up 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 file 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`
##### Table: Crontab Fields (Linux Crontab Syntax):
| Field | Description | Allowed Value |
| ----: | ------------ | --------------------------: |
| MIN | Minute field | 0 to 59 |
| HOUR | Hour field | 0 to 23 |
| DOM | Day of month | 1-31 |
| MON | Month field | 1-12 |
| DOW | Day Of Week | 0-6 |
| CMD | Command | Any command to be executed. |
##### 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}`
